Ever since the installation of 12.4, Firefox only starts in a small window. I'm getting really pissed about that. Does anyone know how to fix that? Any kind of help would be really appreciated!!!

How did you installed Firefox? I guess, you are not using Ubuntu but another derivative such as Lubuntu or Xubuntu. Can you ensure this? – Anwar Shah Sep 8 '12 at 0:30

This usually happends when the localstore.rdf file is corrupted.

It is located in ~/.mozilla/firefox/<profile_name>/.

You can use either of the following solutions:

  • If you have a backup copy of localstore.rdf file from a working profile, a quick remedy is closing Firefox and overwriting the localstore.rdf file in the Firefox profile folder with your backup copy.

  • If you don't have a backup copy just delete the file from the path mentioned above, and Firefox will generate a new copy for you.

  • If you're using Firefox 15, just reset the firefox profile from History > Reset Firefox.

    Important Note (if you're using Reset Firefox):

All of your Firefox settings and personal information is stored in your profile folder. The reset feature works by creating a new profile folder for you while saving your:

  • Bookmarks
  • Browsing history
  • Passwords
  • Cookies
  • Web form auto-fill information

The following items are either NOT SAVED or set to their defaults.

  • Extensions and themes

  • Open tabs, windows and tab groups

  • Site-specific preferences, search engines, personal dictionary, download history, DOM storage, security certificate settings, security device settings, download actions, plugin MIME types, toolbar customizations and user styles

After the reset is finished, your old Firefox profile information will be placed on your desktop in a folder named "Old Firefox Data."

This problem actually went away after I opened Firefox, maximized it, then closed it and I repeated the process multiple times.
