Also, could you please try something in gdb for me too? You'll need to install the debug symbols (firefox-dbg), which are quite large.
If you could do the following, it would be a great help: $ NSPR_LOG_MODULES=Widget:3 firefox -g (gdb) run Once it has started, interrupt it with CTRL+C, and do: (gdb) break GrabPointerError (gdb) cont When the problem occurs again, it will stop (and there should be a message on the console again). Could you then please try: (gdb) p/x sLastUserInputTime What value is it? And is it the same as the timestamp in the error message? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1010466 Title: dropdown boxes on sites stop working To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/firefox/+bug/1010466/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
