Red Hat Bugzilla – Bug 246701
firefox becomes unresponsive when closing tab with flash
Last modified: 2018-04-11 12:08:59 EDT
Description of problem:
When closing tab with some flash animation (for example, youtube video), firefox
becomes unresponsive and have to be killed.
Version-Release number of selected component (if applicable):
I had same problem with FC6 firefox 220.127.116.11 and 18.104.22.168
Often. Only certain flash applications do that. Youtube/dailymotion videos cause
problem almost every time.
Steps to Reproduce:
1. Watch video on youtube.com in a tab.
2. Close tab
Firefox stops responding.
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
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

Hmmm, I run the latest flash from Adobe, with FF 22.214.171.124, 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?
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 126.96.36.199 released today, maybe it will help.
yum install libflashsupport
Will it work in F7 too? I think pulseaudio was added only in F8.
Reporter, could you please, check whether you can reproduce the bug with the
latest Adobe plugin?
Thanks a lot.
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.
I haven't tried too much, but so far, it worked ok with latest flash.
OK, cool, thanks. Please, reopen if it happens again.
