A much easier work-around for most cases is the attached script that runs 'pkill firefox'.
Save it to your desktop, check its contents are not malicious (you always do that, right?) and change permissions to be executable. Then if you get the warning about not being able to re-start firefox, just double-click and run the script, then try again. As a normal user you can't kill the processes of other logged-in users, so if there are other sessions of firefox running for others they won't get stopped. I don't like the idea of regressing Flash, as most updates are important fixes for its Swiss cheese security. Linux is not immune to hacking! Even though Windows get the most attention, one should never ignore security patches for internet-facing software on ANY system.. ** Attachment added: "Kill script for firefox" https://bugs.launchpad.net/ubuntu/+source/firefox/+bug/875538/+attachment/2610501/+files/kill-firefox.sh -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to firefox in Ubuntu. https://bugs.launchpad.net/bugs/875538 Title: [Firefox 3.6.23] Impossible to open firefox because firefox-bin process is still running Status in “firefox” package in Ubuntu: Invalid Status in “flashplugin-nonfree” package in Ubuntu: Invalid Status in “firefox” source package in Lucid: Triaged Status in “flashplugin-nonfree” source package in Lucid: Triaged Status in “firefox” source package in Maverick: Triaged Status in “flashplugin-nonfree” source package in Maverick: Triaged Bug description: After upgrading firefox to version 3.6.23 few days ago, firefox does not work properly. At firt use after computer starting, firefox works well. It is possible to close firefox without any issue. But at second starting, firefox indicates it is impossible to launch firefox because firefox-bin process is still running. The workaround is to restart the computer, or simply kill the firefox-bin process. This behaviour happened right after upgrading firefox to version 3.6.23, and is systematic with the profil user I use (it's an admin user). I tested with another profil (non admin) on the computer: The problem has not been reproduced.
