Windows XP, Service Pack3, all the latest updates done. Scanned for viruses & malware, ran CCleaner. Defragged HD. Reset Firefox, uninstalled firefox & reinstalled. The only thing I haven't done is throw away my user profile. I exported my bookmarks to an HTML file so I can restore them. Will that work?

It is possible that your security software (firewall, anti-virus) blocks or restricts Firefox or the plugin-container process without informing you, possibly after detecting changes (update) to the Firefox program.

Remove all rules for Firefox and the plugin-container from the permissions list in the firewall and let your firewall ask again for permission to get full, unrestricted, access to internet for Firefox and the plugin-container process and the updater process.

See:


Create a new profile as a test to check if your current profile is causing the problem.

See "Creating a profile":

If the new profile works then you can transfer files from a previously used profile to the new profile, but be cautious not to copy corrupted files to avoid carrying over problems.
