I was having the same problem with Firefox/Flash, and I found that the problem was the composite extension..
Check you xorg.con and comment the following if you ever added it:
#Section "Extensions"
# Option "Composite" "Enable"
# Option "RENDER" "Enable"
#EndSection
Restart X and check. It worked for me
p.s. I have an Nvidia Geforce 2 go, Nvidia drivers installed, running X11 R6.8
]]>A note: after a clean install, the three times I try it, gave me the message that a unsupported extension was dissabled. And I do not have any extension installed, only the flash, and the one that do not work.
]]>Weird stuff.
]]>EDIT: Java and mplayer-plugin are working just fine, only Flash is giving me trouble.
]]>Thanks.
]]>I didn't try that hard to get the Arch Package to work--just deinstalled, reinstalled, opened a flash page and said the heck with it.
]]>I don't know the user profile layout that arch built, but the official firefox directory structure looks like
.mozilla -> plugins
firefox
which, I think is slightly different than before.
]]>maybe a reinstallation of the flash-plugin would help?
]]>And they said I was crazy....
]]>Did you choose to upgrade from 0.8 when you were promted?
]]>After upgrading to Firefox 0.9 I don't have flash working anymore. Any ideas as to what's wrong?
