Unable to launch firefox 48 with custom profile using Geckodriver

[furqanmlk]

Meta -

OS: Win 10 x64

Selenium Version:
3.0
Browser:
Firefox

Browser Version:

Firefox 48.0.1

Expected Behavior -

geckoriver should launch Firefox48 with custom profile

Actual Behavior -

geckodriver still launches Firefox with new profile

Steps to reproduce -

01: Zip default profile folder

02: Getting default profile location

string prof = (@"...\AppData\Roaming\Mozilla\Firefox\Profiles\6uqm9vnl.default.zip");

03: Converting to base64-encoded string
var prof1 = System.Text.Encoding.UTF8.GetBytes(prof);
var prof2 = System.Convert.ToBase64String(prof1);
FirefoxProfile profile = new FirefoxProfile(prof2);

04: Initializing FirefoxDriver
new FirefoxDriver(profile);

I can confirm the issue, I have the same problem and tried everything without any success ...

[borginek]

[furqanmlk]

With v3.0.0b2 and geckodriver 0.10, I was able to do so with following code (sorry im using vb.net, ull have to convert it yourself)

    Dim FirefoxSrvc As FirefoxDriverService = FirefoxDriverService.CreateDefaultService()
    FirefoxSrvc.FirefoxBinaryPath = "C:\Program Files (x86)\Mozilla Firefox\firefox.exe"
    FirefoxSrvc.HideCommandPromptWindow = True

    Dim FirefoxOpts = New FirefoxOptions
    Dim FFLocalProfile As FirefoxProfile = New FirefoxProfile("C:\ff\joeluser")
    FirefoxOpts.Profile = FFLocalProfile

    driver = New FirefoxDriver(FirefoxSrvc, FirefoxOpts, New System.TimeSpan(0, 0, 60))

Hope this helps !

Thanks Scr34mik for your help,

Unfortunately, I am getting error "corrupt deflate stream" at ,
driver = New FirefoxDriver(FirefoxSrvc, FirefoxOpts, New System.TimeSpan(0, 0, 60))

if profile is converted to Base64String
Then it launches Firefox with new profile not desired profile

I can also confirm this issue. Looking for a long term solution to be able to use firefox for GUI tests.

I found that we can use https://github.com/mozilla/geckodriver/releases/tag/v0.7.1 then follow https://developer.mozilla.org/en-US/docs/Mozilla/QA/Marionette/WebDriver step by step.

caps = DesiredCapabilities.FIREFOX
caps["marionette"] = True
caps["binary"] = settings.FIREFOX_PATH
driver = webdriver.Firefox(capabilities=caps)

It just work :)

I get a similar error, when I try to launch custom profile with Selenium
Environment
Firefox 48.0.2
Geckodriver v0.10

Has there been any updates regarding this?

[titusfortner]

Yes, Geckodriver v0.11 (when it comes out) will support 'firefoxOptions' - mozilla/geckodriver#228

[iKarthik]

Is there an expected release date for v0.11?

[furqanmlk]

Following` code is working !

FirefoxDriverServise service = FirefoxDriverService.CreateDefaultService();
FirefoxProfile profile = new FirefoxProfile();
profile.AddExtension(Path.GetFullPath("path/to/extension.xpi"));
var options = new FirefoxOption();
options.Profile = profile;
var driver = new FirefoxDriver(service,options,TimeSpan.FromMinutes(30));

Hi furqanmlk, I tried your code but it still has the same error, I'm using the latest version for both selenium and geckodriver, could you please confirm this, thank you!

I had a working setup with 0.11.1 and a custom profile (FFv49.0.2) for days. Then I did two things that screwed it up. I upgraded my Selenium.Support Nuget from 2.53.1 to v3 (to match my installed Selenium of v3.0) and installed Mozilla Nightly. I have no idea why either of those things would make it break, but it did. I started getting the "corrupt deflate stream" errror.

I just got it to work again. I uninstalled Nightly. I then went back to my 49.0.2 mozilla and used firefox -P to create a new profile in a new directory. Set it to use that by default. Then I ran my code again, pointed to that new profile directory. It worked. So my speculation is that something in the profile itself is getting corrupted OR the Nightly installation modified my testing profile somehow. Although I thought we were supposed to be using Nightly for best results..

Try to remove 'user.js' file from profile directory.

[wcdeich4]

How can I use my real FireFox user profile? (The existing profile that is used when I open FireFox every day.)

The examples @furqanmlk and @Scr34mik provided are actually creating a new profile. Maybe you can reuse the created profile - but it not my real user profile.

Using the real user profile is highly advantageous b/c sometimes there are firewall popups & security questions. My real profile has already answered those questions & won't be challenged again. A profile created by Selenium will get blocked by firewall popups in the middle of the automation test.

[asrafiq]

Older version of Firefox picked up the existing profile but now it creates a new profile for each test. can this be fixed please? The works on Chrome and IE like it did on Firefox before.

[titusfortner]

Geckodriver allows you to pass in the Base64 encoded zip of a profile directory (including your default) - https://github.com/mozilla/geckodriver#firefox-capabilities

The specifics on how to generate the correct Options parameter will vary based on which language bindings you are using.

Let's suppose this issue was fixed in geckodriver 0.11 (current version is 0.18)
Feel free to reopen it if it's not true.
