Bug Description
After flash file execution (with Macromedia flashplayer) Firefox usually hangs.
(That is, the flash execution occurs, but when exiting it by typing another URL,
for example, firefox usually hangs).
This does not occurs with previous Firefox versions, or by using Epiphany.

Does it for me too,
Try viewing disney.go.com for more than a few minutes.
I've tried ARGB_VISUALS= 1 in /usr/bin/firefox but to no effect.
export XLIB_SKIP_
(I already have ALSA mixing anyway)
Sometimes strace -p on firefox jerks it out of the "hang" but not always, it
gets stuck again though, it gets stucj in this poll:
select(0, NULL, NULL, NULL, {0, 11000}) = 0 (Timeout) {1132871877, 902792}, NULL) = 0 {1132871877, 913977}, NULL) = 0 POLLIN| POLLERR| POLLNVAL, revents=POLLIN}], 1, -1) = 1 1\20\0\ 0\0", 8) = 8
gettimeofday(
select(0, NULL, NULL, NULL, {0, 11000}) = 0 (Timeout)
ioctl(38, 0x54a1, 0x90e425c) = 0
gettimeofday(
poll([{fd=38, events=
read(38, "U\205E\
read(38, 0xbfbc8584, 8) = -1 EAGAIN (Resource temporarily
unavailable)
poll(
which strace can pull it out of, so can quitting strace pull it out too. Maybe
it aborts the poll systemcall?
SIGSTP and SIGCONT also seem to recover it.
I think it is more likely ot happen if there is more than one firefox instance
on the page.
It happens with the mozilla non-free flash plugin or one of the free ones.
Maybe its to do with alsamixer? If I remove "aoss" in firefox/ mozilla- firefoxrc and put in "none" then apart from sound
/etc/mozilla-
still mysteriously working in flash (it doesn't in epiphany) it also doesn;t
lock up.
So maybe this is really an alsa bug related to poll??
