Favourite add-ons vanish between sessions

Posted

When I boot my computer lately,about three of my favourite FF (ver 33.1.1) add-ons are no longer installed.These include Lazarus,X-notifier,and Theme Font and Size Changer.I can reinstall them manually,but it is becoming a pain to do so.I find that when I DO reinstall,the add-ons seem to remember my previous settings,such as X-notifier,which still has my Hotmail accounts and passwords when I reinstall it. Please advise,thanks!

After reading that article and all the comments, it ends with a post by Lukas (of avast!, I assume) saying:

"The Browser Cleanup team is now working on a fix, which will be delivered via a VPS update shortly (tomorrow)."

So that's promising!

Firefox doesn't make any configuration changes at Windows startup, although its background service may check for updates.

There are other programs that may do a little browser cleanup at Windows startup, including CCleaner. I haven't previously heard of losing extensions, but if you use CCleaner or a similar browser privacy tool, you might want to try deactivating it as a test to see whether that works around this issue.

Hi XRaiderV18, do you have any privacy or utility software that may run at Windows startup and clean up browser settings? In addition to looking at CCleaner, I also would check Advanced SystemCare or similar utilities.

the only utility software that runs at startup is my antivirus, and with regards to ccleaner, I'd need a professional who knows what they're doing to look it over.

Hi XRaiderV18, do you mind mentioning your brand of antivirus software? The sudden appearance of this issue could be a new "feature".

Regarding CCleaner, if you are not running it, then please ignore that part. (It has settings to clean up browser data such as history and cookies when you reboot Windows.)

Excellent detective work! I DID recently update FF and am running the free version of Avast! Just unchecked Browser Cleanup as well.
