In a similar vein, some of the major financial sites are beginning to program their sites for either IE7 or FF3.... and ONLY those browsers. We may well need to find a user agent string that works there IF or WHEN these changes occur.
The fix is spoof the firefox version that they want.
You can use kko's page to hone the prefs.
Some ideas how the detectors are made trenchant.
Currently state of the art boils down to make empty vendor pref.
Makes Standard User Agent string look like:
Mozilla/5.0 (Windows; U; Windows NT 5.1; de-DE; rv:220.127.116.11) Gecko/20081217
But leaves no loop hole when You spoof FPox.
Another is add vendor comment NO Firefox plus version - that lets them detect what You want (their scripts overlook NO)
It is in flux.
You are not the only that visits places with a bad browser switch.
We all have to keep updated.
