You have a corupted user agent:

Mozilla/5.0 (Windows; U; Windows NT 5.1; fr; rv: Gecko/20100722 Firefox/3.0.10 MEGAUPLOAD 1.0

You have or had an extension installed (MegaUpload toolbar) that has changed the user agent from Firefox/3.6.x to Firefox/3.0.x.

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.
