For a way to do it: Simply load 6 to 10 tabs (what you want, I have gmail, ubuntuforums, and various always changing web sites). And then, if you switch back and forth from your Firefox to other applications like Writer, Impress or the Gimp (and maybe others), the problem will happen after a while. The "after a while" is difficult to specify, but if I start in the morning, it usually crash in the afternoon... So it is quite long. It seems to be quite reliable here to reproduce, as it crashes everyday once. But it costs time to reproduce...
Note that Firefox is taking about 100MB of memory after 5 hours of usage, so I do not think that there is a memory leak. -- Firefox crashes often when switching from an application to it https://launchpad.net/bugs/96446 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
