I also noticed it in many distributions and different Firefox versions.

One thing I've found that helps with Firefox and Flash on various Linux distros
(I use Fedora Core) is to set this environment variable in the firefox startup

Comment 3 Christopher Aillon 2007-11-26 07:21:35 EST
That env variable should only needed for older flash.  We used to export that in
the startup script, but the newest flash from adobe.com should not require that
any longer...

Hmmm, I run the latest flash from Adobe, with FF, and without that
environment setting, it crashes all the time. After I put it back in there, my
browser stays up for days (compared to minutes/hours without it, every site has
flash these days it seems...).

I'm using Shockwave Flash 9.0 r48, is there a newer version I should use?
Comment 5 Pavel Rosenboim 2007-12-04 02:00:55 EST
XLIB_SKIP_ARGB_VISUALS=1 didn't help in my case. I think the problem happens
when flash has to play audio. 

BTW, new flash plugin released today, maybe it will help.

yum install libflashsupport
Comment 7 Pavel Rosenboim 2007-12-04 04:50:27 EST
Will it work in F7 too? I think pulseaudio was added only in F8.
Comment 8 Matěj Cepl 2007-12-05 09:48:21 EST
Reporter, could you please, check whether you can reproduce the bug with the
latest Adobe plugin?

Thanks a lot.
Comment 9 Matěj Cepl 2008-01-17 08:34:02 EST
Reporter, could you please try to reproduce this issue with the last flash
plugin, please? Upgrade please to that and tell us whether it helped.

Concerning Pulseaudio -- yes, it is available in F7, but it is not default and
you can live without it.
Comment 10 Pavel Rosenboim 2008-01-17 08:37:35 EST
I haven't tried too much, but so far, it worked ok with latest flash.
Comment 11 Matěj Cepl 2008-01-17 12:51:35 EST
OK, cool, thanks. Please, reopen if it happens again.
