Hi, It would be great firefox-profile-js for implement ProfilesIni to get the directory of profiles based on name from default firefox profiles path (example: C:\Users\User\AppData\Roaming\Mozilla\Firefox\profiles.ini)

Use cases: Tweak few testing profiles while on manual testing and use it on automated testing.

Selenium Java example

// Choose the browser, version, and platform to test
DesiredCapabilities capabilities = DesiredCapabilities.firefox();

capabilities.setCapability("platform", Platform.XP);
FirefoxProfile profile = new ProfilesIni().getProfile("UsernameProfiles");      
//profile.setPreference("browser.cache.disk.enable", false);  

capabilities.setCapability(FirefoxDriver.PROFILE, profile);

this.driver = new RemoteWebDriver(
            new URL("http://localhost:4444/wd/hub"),
            capabilities);

files like firefox-profile.sublime-project should not be shipped to npm.

archiver api has changed, and archiver.bulk() has been replaced by...? It seems like archive.glob() should be used instead

profile.setAssumeUntrustedCertIssuer(false);
profile.setAcceptUntrustedCerts(true);

Even after setting these options, I get the following error:

Your connection is not secure

The owner has configured their website improperly. To protect your information from being stolen, Firefox has not connected to this website.

Downstream projects from this one are receiving security vulnerability notifications from GitHub: Known high severity security vulnerability detected in adm-zip < 0.4.11 defined

It looks like this project already has "adm-zip": "~0.4.x" in the package.json so a fresh npm install and release to npm should fix this?

Hi,

I'm automating some tests that require a base64 firefoxProfile to be imported (see mozilla/geckodriver#755). I've used the CLI to create it, like this:

node_modules/.bin/firefox-profile -c firefoxProfile -b

However when running the tests the following Error is thrown:
ERROR: Last unit does not have enough valid bits

I'm running selenium-standalone both in node and hub, more info:

Versions: Selenium standalone : 3.4.0
Geckodriver : 0.16.1
Firefox (Windows) : 53.0.3

I'm importing the profile in the config of webdriver.io:

  maxInstances: 5,
  browserName: 'firefox',
  marionette: true,
  acceptInsecureCerts: true,
  log: {
    level: 'trace'
  },
  'moz:firefoxOptions': {
    profile: 'profileBase64'
  }
};

I've generated the firefoxProfile forlder following the steps specified in:
https://support.mozilla.org/en-US/kb/profile-manager-create-and-remove-firefox-profiles#w_creating-a-profile

I'm running selenium-standalone hub on Mac OS X 10.11 and the node on Windows10, I've tried to create the profile on both systems and run the tests on the same machine that is running the hub.

the config is imported, since I get the following on the node log:

09:45:31.206 INFO - Creating a new session for Capabilities [{rotatable=true, marionette=true, log={level=trace}, acceptInsecureCerts=true, loggingPrefs=org.openqa.selenium.logging.LoggingPreferences@6448c9d7, locationContextEnabled=true, browserName=firefox, javascriptEnabled=true, handlesAlerts=true, moz:firefoxOptions={profile=profileBase64}, maxInstances=5, requestOrigins={name=webdriverio, version=4.6.2, url=http://webdriver.io}}]

Not sure what I' doing wrong should I be passing any other option when running the CLI on terminal?

Thanks.

When trying to install via NPM I get this error:

Hello, could you update your link to selenium-webdriver's link to the example in Selenium hq, it's broken, thanks!

http://seleniumhq.github.io/selenium/docs/api/javascript/module/selenium-webdriver/firefox/index.html

Attempt to set a proxy using following syntax

myProfile.setProxy({proxyType: 'manual', httpProxy: '127.0.0.1:8080'});

does not work for latest Firefox 27.0.1. The reason for this is that Firefox expects an integer value for network.proxy.http_port and in your code you try to set it to string value:

this.setPreference('network.proxy.' + key + '_port', hostDetails[1]);

The easiest fix is to convert string to integer using parseInt function:

this.setPreference('network.proxy.' + key + '_port', parseInt(hostDetails[1], 10));

Pull request will follow soon.

I try to use this code with directConnect: true:

var makeFirefoxProfile = function (preferenceMap) {
  var deferred = q.defer();
  var firefoxProfile = new FirefoxProfile();

  for (var key in preferenceMap) {
    firefoxProfile.setPreference(key, preferenceMap[key]);
  }

  firefoxProfile.encoded(function (encodedProfile) {
    var capabilities = {
      browserName: "firefox",
      firefox_profile: encodedProfile
    };

    deferred.resolve(capabilities);
  });
  return deferred.promise;
};

  getMultiCapabilities: function () {
    return q.all([
      makeFirefoxProfile(
        {
          "browser.download.folderList": 2,
          "browser.download.dir": "D:/Automation",
          "browser.helperApps.alwaysAsk.force": false
        }
      )
    ]);
  },

But it show error when start server:

I have wonder that profile = caps.get(Capability.PROFILE) return string, and getTemplateDir() {return this.template_;} is function in class Profile at node_modules\protractor\node_modules\selenium-webdriver\firefox\index.js
I don't know how to fix it.

Hi, I am trying to use your firefox-profile to disable flash plugin on browser. I am using remote web driver capabilities to run a test on browserstack.com. Here is the code snippet:

https://gist.github.com/chindoshi/8536187

The test runs fine but I don't see the flash being disabled on browser. Flash widgets still work.
Is this supported or is there any problem with code itself ?

While running web-ext unit tests locally I did notice the following error being logged when mocha did run all tests and it is exiting:

[firefox-profile] cannot delete profileDir on exit /tmp/firefox-profile2Tntmz/ TypeError: fs.rmSync is not a function
    at FirefoxProfile._cleanOnExit (/.../web-ext/node_modules/firefox-profile/lib/firefox_profile.js:288:10)

    at process.topLevelDomainCallback (domain.js:138:15)
    at process.callbackTrampoline (internal/async_hooks.js:124:14)

As the stack trace shows the error seems to be related to the changes introduced in #126 and released on npm as part of [email protected].

Based on a very quick look I think that the exception is actually expected, because fs is actually set to the "fs-extra" here:

• firefox-profile-js/lib/firefox_profile.js

  Line 9 in f77a86f

  fs = require('fs-extra'),

and rmSync doesn't seem to be part of the API exposed by "fs-extra" npm package (where it seems that only removeSync is actually available), unlike the native nodejs "fs" module which does actually have an rmSync method with that signature.

Looking more closely to the fs-extra removeSync function (which was also what that method used to call before #126), it seems that it should be already calling fs.rmSync internally on nodejs version where it is actually available:

• https://github.com/jprichardson/node-fs-extra/blob/a84ef6dd8969f57d16e23267e1790def791e9a82/lib/remove/index.js#L13-L17

And so it seems that rolling back to the previous implementation (the one already being calling fs-extra removeSync) may be actually a reasonable fix for this issue and should still remove that directory as the new version was meant to ensure.

On node 0.10.25
Using firefox-profile version 0.2.7

var FirefoxProfile = require('firefox-profile')
        var profile = new FirefoxProfile()
        profile.setPreference('network.http.prompt-temp-redirect', false)
        profile.setPreference('app.update.silent', true)
        profile.encoded(function(profile) {
            var capabilities = Webdriver.Capabilities.firefox()
            capabilities['firefox_profile'] = profile
            var browser = new Webdriver.Builder()
                .usingServer(server.address())
                .withCapabilities(capabilities)
                .build()
            callback(browser)
        })

The error is on the instantiation of FirefoxProfile. Any idea what is going on?

Here's a gist of what I get from terminal: https://gist.github.com/lloydwatkin/9931047

Tried to show the default homepage on firefox.
But it didn't show the home page and it seems the options is not set. Any idea?

Hi,

I'm on Mac os, I've tried recreating the example from the readme, there are no errors, and the browser starts, but the proxy settings I tried to add didn't catch (when I open the network settings they're set to system proxy instead of the one I tried to set.

I've looked in the temp directory and found a bunch of directories with files called profile.zip (sized 22 bytes).

Any advice for me? This is the code I'm using:

var fp = new FirefoxProfile();
fp.encoded(function(encodedProfile)
{
    browserCapabilities.set('firefox_profile', encodedProfile);

    // you can set firefox preferences
    fp.setPreference('browser.newtab.url', 'about:blank');
    fp.setPreference('browser.tabs.drawInTitlebar', false);
    fp.setPreference('browser.urlbar.trimURLs', false);

    fp.setPreference("network.proxy.type", 1);
    fp.setPreference("network.proxy.http", proxyServer);
    fp.setPreference("network.proxy.http_port", o.proxy.port);

    fp.updatePreferences();
    var driver = new webdriver.Builder().
       usingServer(serverAddress).
       withCapabilities(browserCapabilities).build();
});

    var description = doc[rdf + ':RDF'][rdf + ':Description'];
                                       ^
TypeError: Cannot read property 'xmlns:Description' of undefined

It is failing because Firebug's install RDF does not namespace RDF or Description nodes.

I am unable to set the browser.download.dir preference. I'm not sure if this is a Firefox issue or not.

If I call setPreference("browser.download.dir", "C:\Temp"), the download directory gets set to C:Temp. It strips out the backslashes no matter what I do and ends up using the default downloads directory.

For headless e2e testing, I am using Debian's Firefox fork called iceweasel. firefox-profile doesn't seem to effect iceweasel at all. I am using this pluging to click on a download link an download automatically with settings in profile. It works on a Mac Firefox, but not debian. Any suggestions, please?

root@jenkins-agent-nodejs-001:~# firefox --version

I'm seeing this in a separate project, but I think it's coming from this module (specifically /lib/firefox_profile.js:691)...

var folderName = path.resolve(path.join(os.tmpDir(), uuid.v4() + suffix + path.sep));

DeprecationWarning: os.tmpDir() is deprecated. Use os.tmpdir() instead

Hi.... thanks for creating firefox-profile. It's been helpful. I ran into one issue that I figured I'd let you and your users know about. Maybe I'm just doing something wrong, but when I pass the "capabilities" object into selenium-webdriver, /selenium-webdriver/firefox/index.js eventually attempts to encode your module's profile object, which is already encoded before being passed in.

I'm using selenium-webdriver v3.0.0-beta-2

On line 486 of the firefox/index.js file, there is this set:
caps.set(Capability.PROFILE, profile.encode());

Your profile object doesn't have an encode() function, so an error is thrown. In your examples, you have us call .encoded() on the profile and then set the encoded object that we get back in the callback as the 'firefox_profile' of the capabilities object. It's already encoded by the time selenium's code tries to encode it with a function that doesn't exist on your object.

To get around this, I had to patch line 486 in the selenium driver file to:
caps.set(Capability.PROFILE, profile);

Obviously, that's a bad workaround since it breaks updates of selenium and I guess violates their idea of what functions a profile object should have. It would probably be much better if you added a synchronous function called "encode()" that does exactly what "encoded()" does asynchronously. If a synchronous function would be bad for some reason (sorry, I haven't read all of your code) maybe you could hack it with "encoded()" setting a flag on the object, and "encode()" just returning the profile object itself if the flag is set?

Thanks again for your work, and if there is some option I don't know about to get around this issue correctly, I'd appreciate hearing about it.

Best,
Dan

I see that when running firefox using protractor, several directories with the name pattern /tmp/tmp-<random> are created in addition to the profile directory (which is returned by FirefoxDriver.prototype.path).

When using shouldDeleteOnExit(true) to create the profile, I see that the profile directory gets deleted. However the tmp-* files do not get cleaned up. I think that should also get deleted when this flag is enabled.

Hello Saad! I have issue loading an extension built with the new WebExtensions format

This code here looks for package.json:

AFAIK package.json is not used anymore

  // Attempt to parse the `install.rdf` inside the extension
  var doc;
  try {
    doc = fs.readFileSync(path.join(addonPath, 'install.rdf'));
  }
  // If not found, this is probably a jetpack style addon, so parse
  // the `package.json` file for addon details
  catch (e) {
    var manifest = require(path.join(addonPath, 'package.json'));
    // Jetpack addons are packed by default
    details.unpack = false;
    details.isNative = true;
    Object.keys(details).forEach(function (prop) {
      if (manifest[prop] !== undefined) {
        details[prop] = manifest[prop];
      }
    });

    cb && cb(details);
    return;
  }

I don't have time to investigate this further, but I might in a few days.

This library can actually be used together with Protractor (which uses selenium-webdriver). And since I did not find out how to use the functionality from selenium-webdriver to achieve the same result, I would say it is easier.

I made an example of using it with Protractor in this issue.
The important part is to set the encoded profile on .moz:firefoxOptions.profile instead of on .firefox_profile.

npm install outputs:

npm WARN deprecated [email protected]: wrench.js is deprecated! You should check out fs-extra (https://github.com/jprichardson/node-fs-extra) for any operations you were using wrench for. Thanks for all the usage over the years.

When passing the encoded profile to Selenium, I am receiving the error UnknownError: oversubscribed dynamic bit lengths tree. This appears to be a problem with with adm-zip module.

Hello,

What exactly is the added value of this library compared to selenium-webdriver/firefox?

There is a windows path error when trying to load extensions.

Hi, I'm thinking about porting this to work with Thunderbird as well, as it'd aid some extension development I'm doing.

Is this something you'd be interested in including in this repository? If not, I'll happily fork this into a separate project.

Hi,

Is there a way to set an environment variable for the firefox process? Please see this question for details.

I want to pass the DISPLAY environment variable like in the linked question.

Is that in the scope of this plugin? Technically possible?

Thanks!

seems to be related with firefox version: a travis build on the same git hash passed when ff version was < 30 (~2 months ago), now (the test uses saucelabs latest version of ff).

    fp.setPreference('extensions.firebug.defaultPanelName', 'console');
    fp.setPreference('saadt.coucou', 'console');
    // if the following line is not there, the preferences are not in about:config after the browser starts
    // fp.updatePreferences();
    // you can install multiple extensions at the same time
    fp.addExtensions(['./test/extensions/firebug-2.0.1-fx.xpi'], function() {
        fp.encoded(function(zippedProfile) {

The profiles should be executed on Firefox to make sure (ie test) that they work.

To be done when breaking compatibility...

When I try to apply a user pref, the preference end up in the user.js file, but is not applied. Where is an example (similar code with python selenium works well):

var webdriver = require('selenium-webdriver');
var fp = require('./spec/test/utils/firefox_profile');
var f = new fp();
f.addExtension('./spec/extensions/firefox/test-autoupdate.xpi', function() {
    // create and add profile to capa
    f.setPreference('browser.newtab.url', 'http://www.google.com');
    f.updatePreferences();
    var capa = webdriver.Capabilities.firefox();
    //capa.set('firefox_profile', f.encoded());
    var wd = new webdriver.Builder().
              withCapabilities(capa).
              build();
    wd.get('http://saadtazi.com');
});

I noticed that jetpack-id is deprecated, can this be replaced with something else? It's getID below:

If it's still the only/correct way to do it, should jetpack-id be un-deprecated? It looks to me that it still makes sense for WebExtensions https://github.com/mozilla-jetpack/jetpack-id/blob/master/index.js

cc @rpl because he mentioned it in mozilla/web-ext#2047 (comment)

Very curious to see if you know why no error-handling would be required here:

  let driverPromise = new Promise(function(resolve){

    var capabilities = webdriver.Capabilities.firefox();

    fp.encoded(function(encodedProfile) {
      capabilities.set('firefox_profile', encodedProfile);

      var wd = new webdriver.Builder().
      withCapabilities(capabilities).
      build();

      resolve(wd);
    });

  });

surely an error could be raised somewhere here, how could I handle it?

The reason I bring the issue up here, is so that your Readme could be updated accordingly (or examples, whatever).

thanks!

./node_modules/.bin/firefox-profile -v   -o `pwd`/A

I claim:

• should create a profile at A, with the default user.js

Why this doesn't? cli.js does this instead

  cb(null, new FirefoxProfile({
    destinationDirectory: destinationDirectory
  }));

Which never actually makes any files, unless it is copying from an existing profile.

Ideas for solving this welcome :)

Use case: I need blank, portable profiles for re-using during test-runs of addons.

I feel that this could get expensive at scale :

• firefox-profile-js/lib/firefox_profile.js

  Line 104 in ad6690a

  wrench.copyDirSyncRecursive(profileDirectory, tmpDir, {

• firefox-profile-js/lib/firefox_profile.js

  Line 137 in ad6690a

  fs.existsSync(this.profileDir) && wrench.rmdirSyncRecursive(this.profileDir);

I have this:

   fp.encoded(function (encodedProfile) {
      capabilities.set('firefox_profile', encodedProfile);
      var wd = new webdriver.Builder().withCapabilities(capabilities).build();  /// errors here
      resolve(wd);
    });

I get an error:

            // start the browser 
            var wd = new webdriver.Builder().
                      withCapabilities(capabilities).
                      build();

            // woot! 
            wd.get('http://en.wikipedia.org');
        });
   // });

It would be nice if I were able to create a fx profile like so with terminal firefox-profile ./temp/

I just discovered this repo and am going to dig into it, but before I did I wanted to mention/ask something.

In the past year I worked on a clone profile method.

What I did was:

1. I copy the profile folder, and paste it with a new name in the firefox profiles folder: "C:\Users\Vayeate\AppData\Roaming\Mozilla\Firefox\Profiles\new name here", I do this regardless ofIsRelativ=1`, meaning even if it was absolute path, the clone profile, is a relative.
2. I duplicate the entry in profiles.ini and set IsRelative to =1.

Then on startup of this clone profile, sometimes it starts as if its a brand new fresh profile. It should respect and be same as that old profile. Did you witness this?

thoughts

I can see 2.333... options, one that allows to specify a file path, one that allows to specify userprefs directly in command line:

1. --userprefs path/to/json/file: adds an extra step for the user (create a file)
2. (2.1)--userprefs:key value. Note that the key and the value could contain a space if you use quotes: --'useprefs:a key with a space' 'a value with spaces'
3. (2.2)--userprefs key:value: the key cannot contain a : (or any separator that we might choose) because we would have to split on the first :. Note that --userprefs could be used multiple times.
4. (2.3) any param that we don't know about. Spaces in key or value are supported if you use quotes: `--userprefs 'a key with space:a value with space'. It might lead to errors if we add more params

We can implement 1 and 2.1 at the same time.

It looks if we manually terminate a Firefox process using firefox-profile, attempts to remove the profile fails due to the file being locked, throwing an error. More information in jpm issue 120.

Not sure what a good solution for this could be -- retrying on lock? Any ideas, and we can help with a patch.

Firefox only allows signed addons to be installed permanently so I wonder if there's any way for this module to install addons. The source mentions possible installs from a directory (not just an xpi) but I think it only works for Firefox Developer

web-ext seems to be installing the extension after opening the browser:

https://github.com/mozilla/web-ext/blob/8bd0d13f425bbaed6cfc2f8127883c5c43010f1d/src/firefox/remote.js#L139-L143

Is there any other way for unsigned/local/unpacked addons?

Changes the behavior of target="_blank" links. This is problematic for two reasons:

• It doesn't work on Android (see mozilla/web-ext#1592 for example)
• Dependent libraries have very confusing behavior as a result, so that when I'm testing web-extensions my links misbehave. I thought at first it was a browser bug (https://bugzilla.mozilla.org/show_bug.cgi?id=1598947).

If there's a good reason to change default behavior like that, it'd be good to state why in a comment at least? :)

Super-minor bug

Could use https://www.npmjs.org/package/lodash.clone
