I am also someone experiencing the problem of browser freezes when navigating away from flash pages, or closing flash pages.
One thing I found through trial and error was that the freezing problem went away when I disabled my onboard sound chipset, making me wonder about the audio driver, alsa, flash, or some interaction therein. I posted this in a thread on the ubuntuforums and someone else with a similar sound chipset reported that when they disabled their onboard sound and used a standalone sound card instead their freezing problems stopped as well. The thread in question is here: http://ubuntuforums.org/showthread.php?t=340811&page=3 to the other people here experiencing the freezing problem, I am curious to know what sound chipsets you have, and if disabling the sound chipset, either through the bios or other means, causes this problem to stop. Obviously disabling sound isn't a solution to the problem but it might help narrow it down. my sound chipset is a "Realtek ALC888", aka "realtek hd audio", the other person who determined their flash freezing was sound related also reported having a "realtek hd audio" chipset if I issue the command: aplay -l I get the following identification: **** List of PLAYBACK Hardware Devices **** card 0: NVidia [HDA NVidia], device 0: ALC883 Analog [ALC883 Analog] Subdevices: 0/1 Subdevice #0: subdevice #0 card 0: NVidia [HDA NVidia], device 1: ALC883 Digital [ALC883 Digital] Subdevices: 1/1 Subdevice #0: subdevice #0 -- 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
