I'm seeing similar deadlocks of firefox with 100% cpu usage; this is
happening a lot. I have installed firefox-dbg and started firefox with
"-g" under gdb. When I hit Ctrl-C during a deadlock I get this
backtrace:

My guess is that firefox is stuck executing a pretty weird regular
expression:
(gdb) set print elements 0
(gdb) print chars
$5 = (const unsigned char *) 0x7fff7bd12000

Title:
firefox hangs using 100% cpu
Status in firefox package in Ubuntu:
Confirmed
Bug description:
Firefox is hanging with no special pattern. It can be loading a saved
tab, open a new page, using an already opened page. It simply starts
using 100% cpu and becomes unusable, never coming back (>100 minutes).
This is random, happening a lot, but not always.
