This is a pre-Alpha project to port uBlock Origin to Safari App Extensions(Safari 12+ & iOS 9+ support)
pronounced you-block origin (/ˈjuːˌblɒk/
) — you decide what enters your browser.

BEWARE! uBlock Origin is (and has always been) COMPLETELY UNRELATED to the web site ublock.org
.
An efficient blocker add-on for various browsers. Fast, potent, and lean.
uBlock Origin is NOT an "ad blocker": it is a wide-spectrum blocker -- which happens to be able to function as a mere "ad blocker". The default behavior of uBlock Origin when newly installed is to block ads, trackers and malware sites -- through EasyList, EasyPrivacy, Peter Lowe’s ad/tracking/malware servers, various lists of malware sites, and uBlock Origin's own filter lists.
Safari Content Blockers have a filter limit of 50,000. To get around this limitation uBlock Origin uses a seperate content blocker for each filter list. Some filter lists, such as EasyList, will need to be split into multiple lists to fit within Apple's contraints.
To generate a filter list compatable with Safari you can use abp2blocklist to take any AdBlock Plus complatible filter list and make it work with Safari Content Blockers.
Visit the uBlock Origin's wiki for documentation.
For support/questions/help, there is /r/uBlockOrigin on Reddit.
uBlock Origin (or uBlock₀) is not an ad blocker; it's a general-purpose blocker. uBlock Origin blocks ads through its support of the Adblock Plus filter syntax. uBlock Origin extends the syntax and is designed to work with custom rules and filters. Furthermore, advanced mode allows uBlock Origin to work in default-deny mode, which mode will cause all 3rd-party network requests to be blocked by default, unless allowed by the user.
That said, it's important to note that using a blocker is NOT theft. Don't fall for this creepy idea. The ultimate logical consequence of blocking = theft
is the criminalisation of the inalienable right to privacy.
Ads, "unintrusive" or not, are just the visible portions of privacy-invading apparatus entering your browser when you visit most sites nowadays. uBlock Origin's main goal is to help users neutralize such privacy-invading apparatus — in a way that welcomes those users who don't wish to use more technical, involved means (such as uMatrix).
EasyList, Peter Lowe's Adservers, EasyPrivacy and Malware domains are enabled by default when you install uBlock Origin. Many more lists are readily available to block trackers, analytics, and more. Hosts files are also supported.
Once you install uBlock Origin, you may easily un-select any of the pre-selected filter lists if you think uBlock Origin blocks too much. For reference, Adblock Plus installs with only EasyList enabled by default.
Feel free to read about the extension's required permissions.
You can install the latest version manually, from the Chrome Web Store, or from the Opera add-ons.
There is also a development version in the Chrome Web Store if you want to test uBlock Origin with the latest changes: see uBlock Origin dev build.
It is expected that uBlock Origin is compatible with any Chromium-based browsers.
There is also a development version if you want to test uBlock Origin with the latest changes: for installation, see Install / Firefox webext / For beta version
uBlock Origin is compatible with SeaMonkey, Pale Moon, and possibly other browsers based on Firefox: for installation, see Install / Firefox legacy.
uBO mat also be installable as a Debian package:
- Firefox 56-:
apt-get install xul-ext-ublock-origin
- Firefox 55+:
apt-get install webext-ublock-origin
There is no guarantee the package will be available on your specific platform -- in which case, you will have to install from Firefox Add-ons web site.

To benefit from uBlock Origin's higher efficiency, it's advised that you don't use other inefficient blockers at the same time (such as AdBlock or Adblock Plus). uBlock Origin will do as well or better than most popular ad blockers. Other blockers can also prevent uBlock Origin's privacy or anti-blocker features from working properly.

Free. Open source. For users by users. No donations sought.
Without the preset lists of filters, this extension is nothing. So if ever you really do want to contribute something, think about the people working hard to maintain the filter lists you are using, which were made available to use by all for free.
