I am not clear what your problem is and importantly whether you are trying to ask for help with Firefox.

If you have a Firefox problem can you explain what you need help with please. If the problem is with a new Windows 8 operating system you will need to find a suitable forum to discuss that.

A websearch will turn up many suitable fora one possibility is


The people who answer questions here, for the most part, are other Firefox users volunteering their time (like me), not Mozilla employees or Firefox developers.

If you want to leave feedback for Firefox developers, you can go to the Firefox Help menu and select Submit Feedback... or use this link. (You'll need to be on the latest version of Firefox to submit feedback). Your feedback gets collected at http://input.mozilla.org/, where a team of people read it and gather data about the most common issues.

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

Delete the extensions.* files (e.g. extensions.json, extensions.sqlite, extensions.ini) 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 or not compatible extensions in "Firefox/Tools > Add-ons > Extensions" then click the Tools button at the left end of the Search Bar to check if there is a compatibility update available.

If this hasn't helped then also delete the addons.json and addons.sqlite files.
