I have the same exact problem. I am using Ubuntu Feisty x64 with the latest Firefox.
I have tried the following: Installed 32-bit Firefox with Flash Installed 32-bit Swiftfox Used the wrapper to install flash on the x64 Firefox Reinstalled Ubuntu Feisty (Three times). Deleted my profile (Several times) Removed all extensions Searched for duplicate flash installations (there were no duplications) Followed the Mozilla troubleshooting guide Tried Firefox in a terminal window (no errors) What ends up happening is that Youtube will randomly crash the browser and I have to kill the process to get out of it. This happens one out of every five videos I view. I could stop the video, click on another one, pause it then click on another one, exit firefox completely, but no matter what you try it WILL crash when it wants to. This happens on other sites as well. I list Youtube only because I frequent it quite a bit. I watched a video that I found on www.korn.com and it froze when I tried to navigate away from the page. This is probably the most annoying bug I faced yet. My theory is that Adobe released a beta flash plugin as final. -- firefox crashed -- libflashplayer.so https://bugs.launchpad.net/bugs/104470 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
