I've been using Firefox for a while and was pleased, but then it started crashing. This coincided with a message bar at the top telling me some java scripts were blocked. Now a page tells me I have Java scrit diabled, but under Tools, Options I see I have ticks telling me it is enabled. Any ideas please on how I can get Firefox workign again?
They could of corrupted your profile. I might be best to delete the Firefox profile folder and start again, this site shows you how click here back up your bookmarks first otherwise you will loose them when you delete the profile folder, you will loose all the extensions, so make a note of which ones you've installed so they can be re-installed.
After you've deleted the profile folder start Firefox, it will look for the profile folder, which of course has been deleted so it will ask you to create another one.
I future when you've got Firefox working the way you want its worth backing up the profile folder so any extension you install and they start giving problems you'll have a fallback, again that link I gave explains all.
Thanks. i found the problem was the "Noscript" extension which blocks java scripts unless you add the site to a white list. So I can see a message bloking java scripts but even after i add a site to my white list Firefox crashes, but allows the site next site I load Firefox. A bit of a tedious way to add sites so I deleted the extension.
