Using a specific Firefox profile in Selenium WebDriver in C#

Question

I am trying to use a profile I already have set up for firefox with selenium 2 but there is no documentation for C#. The code I have attempted is as follows:

FirefoxProfileManager profileManager = new FirefoxProfileManager();
FirefoxProfile profile = profileManager.GetProfile(profileName);
driver = new FirefoxDriver(profile);

Code that I have seen that is comparible in Java uses ProfilesIni instead of FirefoxProfileManager, but that is not available in C#. When setting up the driver in this way the selenium profile used has all the default settings instead of the settings specified in the profile I am trying to point to.

I am not sure that I am using the correct methods to retrieve the profile, but if anyone has used Selenium 2 with C#, any information would be helpful.

Answer 1

We use such method to load default firefox profile (you can create custom profile and load it):

private IWebDriver driver;  
string pathToCurrentUserProfiles = Environment.ExpandEnvironmentVariables("%APPDATA%") + @"\Mozilla\Firefox\Profiles"; // Path to profile
string[] pathsToProfiles = Directory.GetDirectories(pathToCurrentUserProfiles, "*.default", SearchOption.TopDirectoryOnly);
if (pathsToProfiles.Length != 0)
{
     FirefoxProfile profile = new FirefoxProfile(pathsToProfiles[0]);
     profile.SetPreference("browser.tabs.loadInBackground", false); // set preferences you need
     driver = new FirefoxDriver(new FirefoxBinary(), profile, serverTimeout);
}
else
{
     driver = new FirefoxDriver();
}

We had the same problem that the profile wouldn't load. The problem is in FirefoxProfile (line 137). It only looks for user.js and the profile from Firefox is actually prefs.js

137>> File prefsInModel = new File(model, "user.js");

Hack solution: rename prefs.js --> user.js
