Running FF beta 17 - I go to tools & click addons. Nothing happens - will not open. clicked control/shift/a = same fail. sorry - I cleared cache/cookies + used avg pro to clean + restarted windows 7 64 X and FF = still fail - I see this similar problem historically happened with FF 6 and others. What is wrong? Thx!
Solved! Go to Solution.
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.
Hi Cor-el TY for your response. I started FF in safe mode, [selected help/restart with addons disabled] then I could see the addon list. Then I restarted FF and the problem is fixed. How odd. At least it is working now.
Now I see that todays special probleme swith the new FF include: under "Help" ALL these are not active: FF help + troubleshooting + submit feedback. I am getting >>>OFF<<< this beta update channel. what is WRONG with FF. Corel, thanks for your answers, but i am not a programmer ,and your instructions were very hard to follow, maybe someone with a degree in computer science coudl follow them. thanks anyway
Thx Electra - I removed tab mix plus and the FF help + troubleshooting + submit feedback work again. Will not ever use tab mix plus after this. If an addon screws up FF, i do not use it again.
