Hi STALMIKI,

You should look at this article about that specific issue and the article Preferences not saved. 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!

Thanks bunches, Matt_G! Your last suggestion was the one that worked.

Hi There

  I had the same problem and the way I fixed it, at least it worked for me, is the following:
   1. Go to tools.
   2. Under the tools tab select options.
   3. Under options select tabs.
   4. "uncheck" the first option, this is, open new windows in a new tab instead.

    Once I did this, the hurray annoying page is not opening any more. Hope this will help.
