If you wait a little while and the dafter firefox weenies have their way this problem will disappear ... because firefox won't have a version number any more.
It'll just say something like "this version was up to date when I checked at <timestamp>" or "this version is not up to date, downloading upgrade".
Try reporting bugs against a non-versioned piece of software, or looking up which version has such-and-such fixed in it, or ...
Life for the BOFH is much easier when software has a coherent series of version numbers (3.0, 3.1, 3.11, 4.0, 95, 98, Me, 2000, 2003, XP, 2008, 7, etc etc anyone?) and doesn't change its name every five minutes (what was Firefox called originally then?), and isn't updated more than once every couple of years (WTF is wrong with Office 2000?), and so on.
