I see...
As it wasn't messed up enough that some don't recognize any browser, now the method is changed :mad:
Well, I made my costum, as I had, but..., well, nothing. Changes, changes and more changes.

6) The Gecko build date in the “Gecko/yyyymmdd†token has been frozen to 20100101 for Firefox releases. This means:
* If you want to detect whether the browser is genuine Gecko, search for the strings “Gecko†and “rv:â€. The presence of these two strings will distinguish Gecko from browsers who state they are “like Gecko†in the UA string.
* If you want to determine the Gecko version, first — as noted above — consider carefully whether you can feature-sniff instead. If you must, obtain it from the “rv:x.y.z†string.
If you are presently using the build date or otherwise depending on the exact format of the “Gecko/yyyymmdd†token, stop! In the next major release of Gecko, this will be replaced by the string “Gecko/â€. If you rely on the fact that this will be followed by a date string, you will break.
