Every now and then after i do several reboots, Firefox glitches and disables my add-ons that i have, as well as removes theme that i constantly use, im starting to get tired of this.

Ive done a complete clean install by removing the appdata and uninstalling firefox, worked fine for a bit but then it started back up again this is happening on version 32.0.3 (x86) for win 7 ultimate x64 sp1

The add-ons i use are Adblocker Plus, Flash Video Downloader, Adblock Plus Pop-up blocker and YoutubeHD with theme ASUS red & black

The way i get them back working again is disabling and re-enabling them, and re-downloading the theme, but thats only a temp fix, i want a permanent fix

There is software like Advanced SystemCare with its Surfing Protection feature that can protect files in the Firefox profile folder against changes. If you have such software then check the settings or uninstall this software.

You can also check for problems with preferences.

The most likely cause of such an issue is other software on your computer, especially when it only happens after a reboot.

Boot the computer in Windows Safe Mode with network support (press F8 on the boot screen) as a test.


Create a new profile as a test to check if your current profile is causing the problem.

See "Creating a profile":

If the new profile works then you can transfer files from a previously used profile to the new profile, but be cautious not to copy corrupted files to avoid carrying over problems.
