If your favorite browser is Firefox, chances are you’ve experienced Flash Hell, perhaps just did not realize what it was: the vicious circle of frozen videos with Flash Player 9, then upgrading to Flash 10, which resolves the frozen video issue, but is not recognized by many sites… then using the removal tool to eradicate all traces of the beta before downgrading to 9 again.
With the final version of of Adobe Flash Player 10 released today the pain is supposedly over… so I hoped. Not quite… here’s the error from Citibank’s Credit Card site:
My shiny new Flash 10 is still not recognized as such, the bank site wants me to install Flash 6.4 or later. Hm, I thought 10 > 6.4, but what do I know… what a pain in the Flash flesh. 
If you visit a site with funky JavaScript detection routines, then it’d be good to let that webmaster know about it.
(Traditionally, this has been one of the biggest problems with a new Player release… websites which hard-detect to a particular version, instead of to a minimum version. Even the public betas haven’t fully eradicated it.)
