Issue with Firefox Profiles

[hali4ka]

Hi,

after updating to Firefox 8 I had the problem that my tests were not executed. The browser windows is getting opened but after that nothing happens. After I long search I find out that selenium2Lib uses default Firefox Profile which is in the installation path of the library. For some reason this can not be loaded.

I have fixed this for me locally in this way:

1. in file _browsermanagement.py - line 332 I removed the FIREFOX_PROFILE_DIR so that this line looks like this now:
   browser = webdriver.Firefox(webdriver.FirefoxProfile())
2. changes in firefox_profile.py - method

def init(self,profile_directory=None):

Here are two changes possible depending of this what you want to do:

2.1 if you want to use your own specified profile the method will looks like this:
self.default_preferences = copy.deepcopy(FirefoxProfile.DEFAULT_PREFERENCES)
self.profile_dir = '<PATH_TO_YOUR_FF_PROFILE>'

    self._read_existing_userjs()
    self.extensionsDir = os.path.join(self.profile_dir, "extensions")
    self.userPrefs = os.path.join(self.profile_dir, "user.js")

2.2 If you want that every time anonymous profile is created in the temp folder and used that it will look like this:

    self.default_preferences = copy.deepcopy(FirefoxProfile.DEFAULT_PREFERENCES)
    self.profile_dir = profile_directory
    if self.profile_dir is None:
        self.profile_dir = self._create_tempfolder()
    else:
        newprof = os.path.join(tempfile.mkdtemp(),
            "webdriver-py-profilecopy")
        shutil.copytree(self.profile_dir, newprof)
        self.profile_dir = newprof
    self._read_existing_userjs()
    self.extensionsDir = os.path.join(self.profile_dir, "extensions")
    self.userPrefs = os.path.join(self.profile_dir, "user.js")

Will it be possible to fix this in future releases, so that no code changes are needed after update?

Thanks

Sorry I just saw that actually this is issue for python bindings of Selenium2. SO I am closing this issue.

[j1z0]

what version of the selenium python bindings are you using?

[j1z0]

ok sorry just saw that you closed this issues, please ignore my last comment

[hali4ka]

I am opening this issue again as the problem was not only in the python bindings.

Here is a patch for Selenium2Library. In the file _browsermanagement.py following needs to be changed:
from
if browser_token == '*firefox':
browser = webdriver.Firefox(webdriver.FirefoxProfile(FIREFOX_PROFILE_DIR))

make
if browser_token == '*firefox':
browser = webdriver.Firefox(webdriver.FirefoxProfile())

Can you please change it for future releases?

I noticed the same issue on FF4 / Windows 2003 Server, don't know why, however if I change init to init, I will get python runtime error, saying that default_perferences is not defined

I've added the ability to specify your own firefox_profile_dir when you call open_browser.

Does that fix this issue for you?

Guys I am still facing this issue where open browser in Selenium2Library opens the browser but does nothing. I tried the solution recommended above by editing file _browsermanagement.py but no luck..
Any help is appreciated.

@MamathaNG are you behind a web proxy?

[mamathanag]

Nope. Don't know if this helps but it worked great in chrome.

[j1z0]

Any logs? Or error msgs u can share?

Hey Jeremy,
I did troubleshoot a little bit and found that the webdriver extension that gets plugged into firefox runtime is disabled.
So during the execution I go into the instance of the browser controlled by the script and enable the extension webdriver.xpi.. things work!
I search around and found a way to play with the firefox settings, but no luck. Any idea how I could get the webdriver plugin/extension to be enabled without manual intervention?
I really appreciate your help!

[j1z0]

Strange. It should be enabled. I would try reinstalling Firefox / selenium and see if that helps. Otherwise u can check out this page and try to programmatically set the preferences for webdriver

Cheers,

Alright, I found a fix for this issue and thought will document the same .. maybe it will help someone someday...

First off, Firefox 11 and above is not compatible with Webdriver, so there is really no option to even enable the webdriver like I used to on Firefox 10.
On Firefox Version 10 you will see a blank window of firefox and nothing happens further.... If you check Firefox->Addons->extensions, you will notice that Webdriver Addon is disabled and during the run if you manually enable it , the run will go thru smooth. To automatically enable the webdriver(without manual intervention), do the following :

In the default firefox profile available in Selenium2Library : "C:\Python27\Lib\site-packages\Selenium2Library\resources\firefoxprofile". Click on "prefs" file, right click , select edit.

Add the following two lines at the end of the file.

user_pref("extensions.alwaysUnpack", true);
user_pref("extensions.autoDisableScopes", 0);

---Save and run your test script... Hola!....works instantaneously...........
