Cannot install flash player 10 for firefox 3.5

Friday, July 31st, 2009 only plays HD videos with flash player 10. If you have lesser flash player then you see notice under the video that please upgrade to flash player 10. I upgraded and upgraded but nothing changed.

Problem was that now i had shockwave flash 9 and 10 simultaneously installed. Open Tools > Add-Ons > Plugins then you see which firefox plugins you have installed.

I disabled shockwave flash 9 but then youtube did not show any video at all. Upper right corner is pop-out button and then it showed me notice how i have plugin disabled.

I removed Adobe Flash from Control Panel > Add or Remove Programs but problem did not went away.

Finally i manually deleted:
* NPSWF32.dll
* flashplayer.xpt
* NPSWF32_FlashUtil.exe
from Mozilla Firefox plugins directory.

Then i installed flash 10 fresh as it is supposed to do.
