My Firefox doesn't recognize it being upgraded. It still thinks that its version is 3.5 even though I've been updating and upgrading it regularly, and now have v9.0.1. installed. Why does this happen?

My Firefox doesn't recognize it being upgraded. It still thinks that its version is 3.5 even though I've been updating and upgrading it regularly, and now have v9.0.1. installed. Why does this happen?

I've tried everything possible to sort this out myself. Nothing helps. Installing, reinstalling, upgrading... (even disabling all the add-ons) ...my Firefox still believes that it hasn't been updated since v 3.5.5 (even though in About Firefox the version states to be 9.0.1). Here is the picture evidence of the problem: Picture showing Firefox version in Help menu as opposed to version recognised here

Please help, this is a major issue for me. I really like Firefox and I'd hate to be forced to install some other browser. Thanks for any help solving this issue.

Your user agent is corrupted by Fast Browser Search (FBSMTWB) and that identifies you as Firefox/3.5.5

see your user agent:

Mozilla/5.0 (Windows; U; Windows NT 5.1; en-GB; rv:1.9.1.5) Gecko/20091102 Firefox/3.5.5 GTB5 (.NET CLR 3.5.30729) FBSMTWB TTLSkins

you must reset user agent

see also these pages and threads about Fast Browser Search (FBSMTWB in the user agent).

Thanks a lot! That worked like a charm! (Just reseting the agent thing). Fast Browser Search I did not have in the first place. But life is good, again! Thanks XXX
