Why can I not see my extensions?

I have extensions and use them every day, but when I look using tools>add-ons>extensions there is nothing there. If I click on appearance or add-ons I see something, but extensions just gives a blank screen. Oh, get add-ons simply says 'loading'.

I know my extensions are there, but why can't I see them? I used to be able to. I use XP and FireFox 17 (I think).

Do you have that problem when running in the Firefox SafeMode?
http://support.mozilla.com/en-US/kb/Safe+Mode
Don't select anything right now, just use "Continue in SafeMode."

When in Safe Mode...

  • The status of plug-ins is not affected.
  • Custom preferences are not affected.
  • All extensions are disabled.
  • The default theme is used, without a persona.
  • userChrome.css and userContent.css are ignored.
  • The default toolbar layout is used.
  • The JIT Javascript compiler is disabled.
  • Hardware acceleration is disabled.

If not, see this:

It is possible that there is a problem with the file(s) that store the extensions registry.

Delete the files extensions.* (e.g. extensions.sqlite, extensions.ini, extensions.cache) and compatibility.ini in the Firefox profile folder to reset the extensions registry.

New files will be created when required.

See "Corrupt extension files":

If you see disabled, not compatible, extensions in "Tools > Add-ons > Extensions" then click the Tools button at the left side of the Search Bar (or click the "Find Updates" button in older Firefox versions) to check if there is a compatibility update available.

If this hasn't helped then also try to delete the addons.sqlite file.

This all seems rather complicated. I was going to try something when I read that all my open tabs would be deleted so nothing has been done yet.

Good news: I noticed that all my plug ins and extensions are visible when using Thunderbird :/
