Hello.

I installed Firefox 19. Immediately most of my add ons stopped working, and in some cases work but not correctly.

Here are some examples: Noia4 - works, but each time I restart Firefox Noia4 reset to default settings. Reminder Fox - Does not work Status4Evar - Does not work - These may be related. Google translator for Firefox, does not work. AnonymoX does not work.

I have not had time to try ALL my add ons, so until I can be sure these work correctly I have returned to v18.

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.

That seems to have cured most problems, thank you

Reminder Fox icon does not appear anywhere, I have tried all locations!
