What's the best way to activate Firebug in Firefox when running Selenium 2?
Edit: Ok, I realize "best" is open to interpretation, but the profile-based solution really used to be a pain with selenium 1.0. So any alternative is considered better until proved worse ;)
You can create your profile in code and dynamically add required add-ons. Let's assume that you saved Firebug XPI into the C:\FF_Profile folder as firebug.xpi (go to Firebug download page, right-click on the "Add To Firefox" and save as C:\FF_Profile\firebug.xpi).
In code:
final String firebugPath = "C:\\FF_Profile\\firebug.xpi";
FirefoxProfile profile = new FirefoxProfile();
profile.addExtension(new File(firebugPath));
// Add more if needed
WebDriver driver = new FirefoxDriver(profile);
