Chosen solution

I did a quick test by using your user agent and got the same message. It is caused by the MEGAUPLOAD in the user agent.

You have or had an extension installed (MegaUpload toolbar) that has changed the user agent from Firefox/3.6.3 to Firefox/3.5.3;MEGAUPLOAD 1.0

You can check the general.useragent prefs on the about:config page. You can open the about:config page via the location bar, just like you open a website. Filter: general.useragent If general.useragent prefs are bold (user set) then you can right-click that pref and choose Reset.
