ln -s /home/user/Downloads/thorium-browser_102.0.4976.0-1_amd64/thorium-browser.desktop /home/user/.local/share/thorium-browser.desktop and in /usr/share/applications doesn't work for me. Did anyone manage to get it working ?

The red color in the tab section is irritating for some peoples eyes.
Would it be possible to change that to its standard font color?

Thank you in advance.

Hi Alex,

great project first of all! 👍

After installation of release .deb file via dpkg -i I wonder why there is an thorium-browser-unstable.list file in my /etc/apt/sources.list.d/ now containing:

deb [arch=amd64] https://dl.google.com/linux/chrome/deb/ stable main

Currenty, I have Chrome stable from official sources installed. So there is a conflict now. Why Thorium needs this additional apt dependency?

Have a nice week

After update to 106.0.5197.0 hardware acceleration stopped working on Wayland, also fonts rendering looks fuzzy. Verified using intel_gpu_top.
It was working well on the previous version (unsure which it was, I'm using deb repo) so my system is configured properly.

subj

First of all, great project! You're doing exactly the things I've wanted for a long time. With that said, would it be possible to get a Flatpak version on flathub perhaps? That way it could be easily installed on a lot of distros without builds for each.

Hi again,

you can set the default browser in Chrom* via settings and inital toolbar button.

Somehow, this does not work for me in Thorium. Default browser is definetly not set.

Do you know what this might cause?

Cheers

hardware vaapi or software?

Thorium info: Version 105.0.5183.0 (Official Build) unstable, built on Ubuntu 22.04, running on bullseye/sid (64-bit)
system info: ubuntu 20.04 x64
CPU: Intel(R) Core(TM) i5-8350U

1. from setting page, hardware acceleration is enabled.

2. from chrome://gpu page, hardware video decode is enabled.

3. use enhanced-h264ify only enable h264.

4. checked the media info while playing video, FFMpegVideoDecoder used.

5. monitored with intel_gpu_top, Video decode always 0.00%

6. confirmed Firefox hardware video decoding is working.

Any suggestions? Thanks in advanced.

System Details

• OS: ArchLinux

Problem
2-finger pinch-zoom is not work, but it can srolling..

I've read the other ticket regarding supporting x265 on linux. However I came across another build that does manage to support x265 on linux.

https://github.com/macchrome/linchrome/releases/tag/v103.0.5060.68-r1002911-portable-ungoogled-Lin64

it requires the --enable-clear-hevc-for-testing command line argument, but it does work.

I've also tried the same command line argument with thorium without success.

Just thought this might be an interesting development.

Could you add Fedora copr?

Hello,

"Chrome and Spotify are writing over 150GB per day to my SSD."

"At the rates I'm clocking I'm actually probably closer
to this group that is showing upwards of 100 GIG
(yes, ONE HUNDRED GIG) of writes to my SSD PER DAY -
just from leaving Chrome open even if I run the awesome extension
(and BTW about the ONLY thing anyone has come up with to indicate
helps this at all by sleeping tabs via the "Great Suspender" extension). "

https://bugs.chromium.org/p/chromium/issues/detail?id=176727

https://www.reddit.com/r/pcmasterrace/comments/54fft5/chrome_and_spotify_are_writing_over_150gb_per_day/

a user seems to have found a solution to avoid the wear of SSD and HHD and huge disk writes of chromium but I don't know if these flah work with the current version, another user said that the excessive storage writes date of chromium is due to cookies to save the state of cookies even in inactive state so should we disable cookies to save our SSDs ?

"I was finally able to fix the heavy disk I/O activity (while idle, and ultra heavy hdd kill while loading pages) by adding the following command line arguments in shortcut:

%pathtoyourbrowser% --profile-directory=Default --disable-cache --disk-cache-size=0 --disk-cache-dir="Z:"

These commands should disable any kind of disk cache except for streaming multimedia - with no noticable speed diff. So the main reason why chrome eats up HDD for me was disk cache - and does so on every version on every variant with any setting in Chrome flags. There is a high chance that your chromium browser variant will not apply these commands on newer versions, however choosing an advanced browser with implemented setting for disk cache location will ensure that cache is not stored (see 360Chrome cn browser option in attachment and i think Slimjet browser also have it, just specify non-writeable location for cache storage). HDD activity while idle and loading heavy pages (example music. torchbrowser. com) in task manager down from 50% HDD to 3-4% (like in FF but FF is still lower I/O both in load and idle and while streaming multimedia). You could do the same with --incognito trick but then your visited history would never be saved.

Hope this helps someone save his HDD/SSD.

https://bugs.chromium.org/p/chromium/issues/detail?id=401391#c7

disable memory cache may be a good ideo to make browser faster but we cant't disable momory cache :

https://stackoverflow.com/questions/69286753/how-do-i-disable-chromes-memory-cache-without-devtools

It will be great if Thorium Browser gives us an effective option to completely disable the cache disk and even the memory disk, maybe it can cancel the excessive session store and speed up the noteooks that have an old HDD and save the SSDs!

Thanks a lot !

Hello, this necessary and important extension because we watch a lot of streaming sites and often there are side black bars and this extension allows to remove them, I tried with Chromium and Ungoogled-Chromium and it didn't work, sure because this extension officially only supports firefox and google chrome, so i had to fiddle around and search and i tried one of these solutions and it worked! please can you add official support for this incredible essential extension, ie add an option to be able to change the aspect ratio of the videos in an easy way without having to manipulate the experimental flags of the browser?

Approach 1
Run the browser with a specific flag.

Quit the browser
Right click on the browser's shortcut and go to Properties
Within the Target box, add --disable-direct-composition-video-overlays` to the end (outside of quotation mark) and apply the changes
Launch the browser
Approach 2
Change graphics back-end for ANGLE.

Launch the browser
Open browser://flags/ (replace word browser, with the one you're using, e.g. chrome://flags/)
Search for ANGLE (full option name: Choose ANGLE graphics backend)
Choose D3D9 or OpenGL
Restart the browser
Approach 3
Disable hardware acceleration.

Launch the browser
Go to browser settings
Search for hardware (full option name: Use hardware acceleration when available)

just installed the newest build from https://thorium.rocks repo (I am on debian) but google sync doesn t seem to work ... should I add my google api key ?

can I maybe ask how ? thanks ! :)

Was trying to compile Thorium on Ubuntu 20.04 and found that 'chromium/src/content/browser/gpu/shader_cache_factory.cc' was missing when running ./build.sh. After creating it, around 22000 of the 55000 targets were built successfully before the second error, which was related to a variable being defined and not being used due to -Werror.

Firstly appreciate the work. Thanks

Could you please add a small script or info what CPUs are supported?

May be like this https://docs.01.org/clearlinux/latest/get-started/compatibility-check.html

(or it is just

cat /proc/cpuinfo | grep avx

Firstly apologies this suggestion was not meant to be impolite.

Would you mind hosting the .deb files at a Ubuntu PPA (1) instead of .rocks site? This is thought in the long term possibility and security in mind.

1. Using a PPA means very challenging for spammers to steal the domain to host fake debs.
2. Or a bounced payment to domain or some errors in payment
3. Or example: https://puri.sm/posts/the-great-purism-dns-outage-of-2018/

This is because browser is a very valuable part. And possibly using PPA would help gain more traction to make the project broader with more devs/maintainers - good for long run.

1. https://help.launchpad.net/Packaging/PPA

Build into web browser default some adblocker like in brave. You can use probably https://github.com/brave/adblock-rust because it is open source.

Hello, here some suggestions of features which can make our favorite browser Thorium Browser even more faster and more efficient, maybe it will be a good idea to add options in the settings to activate/deactivate them quickly with one click, I ask this because I tried to activate some of these flags but it doesn't work :(

secret flag apparently not documented reserved to chrome os:

--enable-native-gpu-memory-buffers

disable complete prefetch to save data date battery:

Back forward cache

Closed Tab Cache

Persistent client hints

option to enable low mode for weak notebook

--enable-low-end-device-mode

increase buffer or media source extension (MSE):

--mse-video-buffer-size-limit-mb=300 --mse-audio-buffer-size-limit-mb=300

increase cache size beyond limit 1.8Gb

--disk-cache-size=5147483647

increase media cache beyond limit 1.8Gb

--media-cache-size=3147483647

disable completely disk cache and memory cache because the flag

--disk-cache-size=0

do not work !

Thanks a lot !

With the last release, my system sees Thorium as "thorium-browser-unstable" even though I'm executing the "thorium-browser" script. Not sure if this is on purpose or not. With the past couple releases, my system would see it as just "thorium-browser".

And this might be nitpicking a little, but the flag "--disable-features=EventPath" is passed twice, once before "--flag-switches-begin" and another time after.

So after downloading of the latest release I did

$ sudo dpkg -i ~/Downloads/thorium-browser_99.0.4821.0-1_amd64.deb                                                                    ✔

$ thorium-browser --help

$ thorium-browser
[1]    6361 illegal hardware instruction (core dumped)  thorium-browser

What are the next steps to determine exactly what went wrong and whether I have to compile manually with which flags?

This is both a feature request and a question. Is it possible to add a patch to support VAAPI on the pure Wayland backend (ozone-platfrom=wayland)? Also, how to apply custom patches to chromium?
Patch link: https://github.com/OSSystems/meta-browser/blob/master/meta-chromium/recipes-browser/chromium/files/chromium-wayland/0001-ozone-add-va-api-support-to-wayland.patch

Hello, i discouver this article of 2016, this problems seems to affect also chromium browsers, it wil be great to save our hard disk and battery to add an option to disable session restore or increase session store intervals, we can do that with firefox but we can't do this with chrome browser, i have made search, i found solution but is complicated , may be it can help, please add option to disable completely session restore, many don't need this feature, we just use browser to watch some videos.....

Thank you in advance !

"Firefox (& Chrome) are eating our SSD's?!"
"Chrome writing to disk every 15 secs"
"Heavy SSD Writes Firefox is eating your SSD"

"Firefox and Chrome can shorten SSD lifetime
September 26, 2016

Firefox and Chrome have been found to continuously write so much data that it might affect the durability of SSDs. Both browsers write an incredible amount of data to disk, even when idle.

firefox-with-32gb-written-in-a-single-day

This was discovered by researcher Sergei Bobik who used the software SSDLife to monitor how much data was read and written on his system. He found both browsers write a lot of data as they continuously make a backup of themselves"

Has anybody found, useing a work around for Chrome, when I looked on the net I could not find anything about Chrome, it was all FF."

"by Nominal Animal
Before switching to a laptop with a really, really fast SSD, I used to keep my active browser profiles on a ram disk (tmpfs).

Essentially, when inactive, your Firefox profile can be stored in a tarball (~/.mozilla/firefox/profilename.default.tar). When active, the contents of the tarball are extracted to a temporary directory on a tmpfs mount (ramdisk), with the ~/.mozilla/firefox/profilename.default pointing to that directory. The only real limitation of this approach is that you'll want to set the maximum cache size to something small; I happily used 0, 32 and 64 megabytes for years. (The no-cache one I used on a 2009 Acer Aspire One A110L minilaptop. It still works fine for casual web browsing.)

There are two approaches to maintaining such Firefox profiles.

First approach is to construct it at login, and deconstruct/repack it at logout. This is managed via a session manager script, and varies slightly between session managers. (I tried to get the necessary hooks for doing this in a transparent, safe manner to GDM, but got fed up with the lack of interest, and switched to LightDM.) The downside is that the profile is in memory even when you don't have a browser open, and if you keep yourself logged in all the time, the tarball version of the profile never gets updated.

Second approach is to customize or interpose /usr/bin/firefox (or /usr/bin/firefox-esr). It is a launcher shell script for Firefox. In it, the exec $MOZ_LIBDIR/$MOZ_APP_NAME "$@" causes the script to replace itself with the actual Firefox binary. If you edit the script, or use your own copy of the script, with the exec removed, the shell will remain in memory while the browser is still running. (In this case, I recommend using dash as the shell, if possible, for minimal resource use.) Before running the browser binary proper, the scriptlet checks if the session symlink points to a valid directory. If not, it sets it up. After the browser binary exits, the script tests if there are no more instances left (ps -o pid= -C firefox or ps -o pid= -C firefox-esr), and if not, re-tars the profile, and removes the temporary profile directory. (I preferred to use sync to ensure the data hits the disk, and notify-send to pop up a notification whenever the profile was safely stored on disk. That way, after making a number of new bookmarks or such, all I needed to do was to close and reopen the browser windows, to be sure they were safely stored on disk.)

For further information, search for firefox profile tmpfs and/or firefox profile ram with your preferred web search engine.

System Details

• OS: Pop!_OS 22.04
• Thorium Version: Version 105.0.5167.0 (Official Build) unstable
• Source of build: deb fetched from thorium.list

Observable Problem

The extensions page chrome://extensions is empty despite multiple extensions installed.

Additional Notes

• I also installed the AppImage, and the same problem persists.
• I installed the regular ol' Chromium deb, this issue does not exist on there, so it must be related to Thorium.

Screenshots

Hello, firstly, great browser!

I'd like you to change the Thorium browser icon to match macOS 11+ style. This is google chrome icon which matches style (square with rounded corners and an icon inside it).

I know that changing icon in macOS is easy and everybody can do it, but couldn't it be better if it was authentic by default?

The preview of the sheet on Thorium 102.0.4976.0 unstable

The preview of the same sheet on Firefox just to show what the sheet should actually look like:

This happens not only with this sheet but all other google sheets. It shows properly for just a few seconds then gets messed up like this.

Hi, you've named the last two releases the 25th and 26th, but it seems they should be the 35th and 36th?

System Details

• OS: Windows 10 21H2

HEVC Videos inaccurately calculate their color profiles leading to color inaccuracy, or simply making the video look more washed out than it actually is.

For comparison I used Muril's patch which doesn't enable hardware accelerated HEVC decoding for this very reason. This issue is effectively asking to stop using StaZhu's patch and instead switch to Muril's patch, which also includes EAC-3/AC-3

Hello.

Is there any way to get an Arm64 Release for Linux?
It will be great on AWS Arm64 linux.

When I set the password store in launch options to any of the three available: <basic|kwallet|gnome> (eg. --password-store=basic), the passwords sync doesn't work. (Just the password sync - the rest of Chrome Sync works fine)

When the option isn't set, also Chrome (since it works there):

Repacked Deb version, CachyOS (Arch-based).

Love the project!

Just wanted to report my test against FireFox Nightly:
using the following video: https://www.youtube.com/watch?v=LXb3EKWsInQ
Thorium shows Render/3D at 100% and Video at 0% in intel_gpu_top, and the video drops frames
FF Nightly shows Render/3D at 25% and Video at 25% in intel_gpu_top, and the video is smooth

12th gen Intel CPU on Kubuntu 22.04

EDIT : After several tests and comparisons with other web browsers and streaming websites, I find that increasing the video buffer depends on the website and not the web browser, for example via the second video player "Dstream", Chrome and Firefox buffer the same quantity even when I modify the parameters of the MSE media source extension of Firefox and the default video buffer of "Dstream" is comfortable (5 minutes video buffer but sometimes other video players only allow a buffer of 40 seconds... .)

https://french-anime.com/animes-vf/1391-bucchigiri.html

but it happens that in other video players, Firefox with the default values buffer full video while chrome and chromium browsers buffer a small amount which penalizes us and jerky palyback when the video is in high definition and the wifi is weak... .

https://livetv767.me/frx/showvideo/1296935_fulham_tottenham/

so we hope Mr Alex will be able to adjust the video buffer parameters like in Firefox, thank you :)

Hello, thank you for this amzing awesome browser 🥇 !!

I have already asked you if it is possible to buffer full video when you have a weak connection to avoid jerks and interruptions....

I did some new research and maybe it can help to enable this important option in chromium browsers :

sometimes the internet connection is weak and it is necessary to buffer full video or increase the size of the video buffering to avoid jerky interruptions on streaming sites and for smooth playback, I found how buffer full video and even buffer youtube videos with firefox browser by putting:

cache_readahead_limit: 999999
cache_resume_threshold: 999999

set media.mediasource.enabled to false

I even made a personal discovery and I discovered that when I deactivate the different types of cache:

set browser.cache.disk.enable, browser.cache.disk.smart_size.enabled, browser.cache.disk_cache_ssl and browser.cache.offline.enable to false

I can buffer full streaming video!!!

but on chrome and chromium, it's more complicated because chrome removed MSE media source extension API from chrome flags....

I tried several things: enable command line and chrome flags to increase buffering in chrome chromium:

--video-underflow-threshold-ms

chrome flag: Increase the nesting threshold before which setTimeout(..., <4ms) start being clamped.

--mse-audio-buffer-size-limit-mb

--mse-video-buffer-size-limit-mb

--enable-protected-video-buffers

--audio-buffer-size --force-protected-video-output-buffers

-enable-swap-buffers-with-bounds

--mem-pressure-system-reserved-kb

--aggressive-cache-discard -disable-back-forward-cache

--enable-protected-video-buffers --mse-video-buffer-size-limit-mb=150 --mse-audio-buffer-size-limit-mb=10

I even installed different scripts for full buffering and even used the console in developer mode:

// Note: Maximize your "browser.cache.disk.capacity" (type "about:config" in Firefox) if you are loading long videos......

I tried all that but failed to enable buffer full video, I tried disabling cache in developer console, and put:

--disk-cache-size=2147483647

--disk-cache-size=1 --media-cache-size=1

but it didn't work, we will be grateful if you have the generosity to find a way or make a script to increase the video buffering or buffer fill video especially when watching full HD video with a weak internet connection which becomes a nightmare, thank you very much !

Hello, thank you very much for this awesome and wonrderful Browser !

Please I have sommes suggestion request to make Thorium Browser even more wonderful ! it will be goog idea to add a new options not found in other browsers, add a button on the main bar to easily enable the Auto Dark Mode for Web Contents chrome flag and quickly disable it, enable reader mode flag recently deleted by chromium (may be integrate brave browser reader open source), buffer whole full video media streaming because some users have a slow internet connection and we need the video loads completely to avoid jerks, so it will be amazing to force have option to force buffer whole full HTML5 Audio/Video for Uninterrupted Playback , and include ad blocker dns by default like controld dns, bancuh dns, adguard dns.....

and an option to control the size of the cache and an option to deactivate the disk cache and activate memory ram cache for more speed because some HDDs are worn and old....

and make a version that uses the same version of chromium used by chrome browser in order to have the latest security patches.....

Thank you very much :)

Will the cookie decryption feature ever be added to give the browser full portability?

Patch for faster scroll web content in the browser

Its a bit strange but on debian sid (XCFE) this browser is not visible on the preferred apps (default browser) also by running the /usr/bin/thorium* ("star" as for a strange reason you install two scripts one as "stable" and the other as "umstable" ) it pauses the profile. I did the installation via your .deb file anyway. IMHO something is broken there or bad mix of scripts. thanks!

Let's be honest if you care about bleeding edge compilation optimizations your probably running arch and not debian.

Hello, I know that Thorium Browser has integrated some Ungoogled chromium options but ungoogled chromum has removed an important option: that of the native chromium ad blocker which blocks heavy ads and also blocks crypto currency mining, I asked ungoogled chromium d 'enable the native ad blocker but I was told using ublock extension is enough, the problem is that there are new ads and new crypto mining technique which uses a small amount of the cpu to do crypto mining , which the ad blocker can't detect, but the native chromium ad blocker

"Chrome sets limits on the resources an ad may use and unloads that ad if the limits are exceeded."

additionally, chromium will apparently migrate to manifest v3 and ad blockers will be less effective.

https://blog.chromium.org/2020/05/resource-heavy-ads-in-chrome.html

a user told me ad blocking is enabled by default in ungoogled chromium

https://source.chromium.org/chromium/chromium/src/+/refs/tags/101.0.4951.54:components/heavy_ad_intervention/heavy_ad_features.cc

ungoogled-software/ungoogled-chromium#1944

but I tested with this test site and ungoogled chromium did not block heavy ads:

https://heavy-ads.glitch.me/

did Thorium Browser remove this native heavy ads blocker, and does Thorium Browser disable the captive portal ?

Thanks a lot !

I build Thorium from sources, set the:
google_api_key
