Everytime I opne FF, it keeps resetting since the last update. I've since tried a fresh install, deleting prefs.js, there was no user.js, restarting without any addons, nothing works.

Any advice would be great, thank you.

What do you mean by 'resetting?' Please explain the problem in detail. What happens? What is/are the exact error message(s) ?

The browser goes to a small size instead of the size I set using my mouse dragging the corner. It's really weird, as even uninstalling then reinstalling still shows the same problem. Also all sites that I go on have reset their zoom back to 100%, I use a 2144 monitor so the font size is tiny at 100%.

Close Firefox. Open your file browser to this hidden location:

  • Mac: *~/Library/Application Support/Firefox/Profiles
  • Linux: *~/.mozilla/firefox/Profiles
  • Windows: %AppData%\Mozilla\Firefox\Profiles
  • *C:\Users\<user>\AppData\Roaming\Mozilla\Firefox\Profiles
  • Windows XP: C:\Documents and Settings\<user>\Application Data \Mozilla\Firefox\Profiles\

Search for the above file. Then rename or delete it. Restart Firefox.
