FF 19 was working fine. Downloaded 20 and within 5 mins. it crashed. Script running problems again and it slows down my internet connection tremendously. I don't want to fix it, I want to go back to FF 19 but can't find it - it doesn't exist Running XP SP 3. If I can't go back to FF 19, then I'll just remove it and stick with Chrome. I like the old private browser in FF 19 better. I run 20 - 40 tabs open at a time and the way the new Private browser works with the existing window open just uses more memory Thanks!

The Reset Firefox feature can fix many issues by restoring Firefox to its factory default state while saving your essential information. Note: This will cause you to lose any Extensions, Open websites, and some Preferences.

To Reset Firefox do the following:

  1. Go to Firefox > Help > Troubleshooting Information.
  2. Click the "Reset Firefox" button.
  3. Firefox will close and reset. After Firefox is done, it will show a window with the information that is imported. Click Finish.
  4. Firefox will open with all factory defaults applied.


Further information can be found in the Refresh Firefox - reset add-ons and settings article.

A possible cause is security software (firewall,anti-virus) that blocks or restricts Firefox or the plugin-container process without informing you, possibly after detecting changes (update) to the Firefox program.

Remove all rules for Firefox and the plugin-container from the permissions list in the firewall and let your firewall ask again for permission to get full unrestricted access to internet for Firefox and the plugin-container process and the updater process.
