Hi Kat565,

You should look at this article about that specific issue and the article Preferences not saved. It might be a pref.js issue. These should give you all the information you need!

If that doesn't work:

  1. Type about:config in the address bar
  2. Click I'll be careful, I promise if prompted
  3. In the Filter input field type startup
  4. Double click on startup.homepage_override_url
  5. Delete the text string and click OK
  6. Close Firefox and reopen the window to verify that it has worked.

Hopefully this helps!

Hi thank you for the reply, this has solved half of the problem but i am still getting a tab for colorful tabs installed on start up. I have tried looking in my profile folders as recommended on their help page but unable to locate the user.js file. The only solution i can find is uninstalling the add on.
