Bug Description

I played several clips in Youtube, using Flash 11... closed the tabs individually, then closed Firefox by means of File/Quit. I expected this to shut Firefox dowqn completely. It didn't, but left the firefox-bin process in a "futex-no".. something state.

Please fix. Firefox version is 3.6.23.
Addons are Ad-blocker and noscript.

Running Ubuntu 10.04.3LTS, all updates.

The update to adobe-flashplugin 11 caused this on every workstation in our school district. After browsing to a page with embedded Flash, firefox-bin doesn't terminate unless killed by hand. We worked around the problem for now by reverting to adobe-flashplugin 10.3, but now users are getting warnings that their Flash plugin is out of date.

Forgot to mention that we ship Firefox 3.6.23 as provided by lucid-updates.

Following up on a suggestion from Alex in question 174159, I checked this on a laptop with ATi graphics (fglrx) and a VirtualBox VM as well as workstations with NVIDIA graphics (nvidia-current) and the problem only occurs on the NVIDIA machines. I have not yet tested with nv.

Several people have suggested upgrading to Firefox 7 from ppa:mozillateam/firefox-stable and that does seem to work around the problem but for our district-wide deployment we prefer to use fully supported Ubuntu packages.

Other folks who are affected, can you comment on the possible NVIDIA connection?
