I can confirm this on a fresh install of Ubuntu 12.04 64-bit: this happened to me two times within the last week already. Just before the fox goes nuts, memory usage is about 2-3G (entire system, not firefox only). And then within few seconds all RAM (8GB here) is gone, the system starts swapping, and is entirely unresponsive. It took me almost a minute from pressing Ctrl-Alt-Esc until the cursor changed to kill- mode, and almost another minute until firefox got killed then. After that, the hogged memory of course gets freed again immediately.
The first time this happened, I was just returning to my machine -- so it was idle for a couple of hours before, and I didn't touch anything: I just saw the hdd led flicker like crazy even before I turned on the monitor. The second time it happened when I opened a web page from a google search -- but only after I enabled JavaScript for that site (NoScript had blocked it before). So as the reporter indicated, JavaScript seems very likely to be involved. One more point *may* be: It never happened to me before Firefox 13.* -- but that may very well be due to the fact that FF 12 was only running for a few days here before getting updated to FF 13 from the repos. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1014234 Title: Firefox hogs all memory and swap To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/firefox/+bug/1014234/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
