When I go to Tools > Add-ons, the page does not work in the following ways:

  • Clicking on Extensions yields a blank frame
  • Clicking on Get Add-ons displays "Loading..." and it never completes
  • Clicking on Appearance yields a blank frame
  • Doing a search always finds nothing

I tried following the steps outlined here: (https://support.mozilla.org/en-US/questions/941626?esab=a&as=aaq), which are deleting extensions.* and compatibility.ini, but that did not help.

Hello nathanb, if you open firefox in safe mode, DO NOT Reset, click the Start in Safe Mode, and then type in location bar about:addons , and then choose extensions, can you see your extensions now ?

if you can see your add-ons in safe mode then maybe a plug-in is the problem (in safe mode the status of plug-ins is not affected), you can try to disable plugins to see if you can correct the issue that way see if another extension is the problem !


EDIT : correct with Strikeout


thank you

I restarted in safe mode and still don't see any extensions. Behavior is the same as when not in safe mode, except that it displays the banner saying that extensions are disabled...

I should note that my extensions appear to actually *work*, they just don't show up.

The issue does not exist in the new profile. It seems to be confined to my current default profile.

Awesome, got it fixed.

I followed ideato's advice above, and everything worked. Except for some reason my browsing session wasn't there--probably my fault for failing to copy one of the files properly.

But anyway, that gave me an idea. So in my existing profile, I deleted some extensions that I thought might be problematic from the extensions/ directory and then deleted the following files:

  • addons.sqlite
  • addons.sqlite-journal
  • extensions.ini
  • extensions.log
  • extensions.sqlite
  • pluginreg.dat

After deleting these files, I started my default profile. Firefox found my extensions and asked me if I wanted to install them -- which I did -- and then everything worked fine again.

Thanks!
