Question

FirefoxProfile ffprofile = profile.getProfile(\"default\");//using firefox default profile
ffprofile.setPreference(\"permiss         


        

Answer 1

Since the dev toolbar CLI does not work for me (since the key combination does not open the CLI) here is how I managed to change profile settings of a running firefox instance:

        IWebDriver driver = //your instance
        driver.Navigate().GoToUrl("about:config");
        driver.FindElement(By.Id("warningButton")).Click();
        IJavaScriptExecutor js = (IJavaScriptExecutor)driver;

        js.ExecuteScript("window.Services.prefs.setIntPref('permissions.default.image', " + 2 + ")");

It's C# but the conversion in Java should not be too hard. The idea is that the about:config tab declares a lot of Javascript object allowing to change the profile settings, so we just have to go on that page and to execute some JS code.
