Public bug reported:

Binary package hint: firefox

launchpad causes high CPU utilization with, and eventually crashes of,
epiphany-browser and firefox-3.0

[Also reported as a bug against epiphany-browser in Bug #323582]

I've had one or two PPA '+archive' pages open in each of epiphany-
browser and firefox-3.0 in intrepid for weeks now, although any
launchpad page will do.  I either lock screen or sleep when away,
usually lock screen.  CPU would always be at around 45% with those pages
loaded, with epiphany-browser and firefox as the top two processes.
edge.launchpad.net made no difference as opposed to launchpad.net.
Eventually, the CPU would climb all the way up to 90% and sit there for
a while, then go up to 100% and crash the browsers.  It takes days until
the browsers will actually crash, though.  Epiphany crashes first; it
seems to be significantly more affected by this than does Firefox.

With all launchpad pages closed, and all of the 8 browser windows with a
sum total of 64 tabs still open, CPU hovers at 10% (+/- 1%).  I should
add that the machine was otherwise idle most of the time both when the
launchpad pages were loaded and after I closed them.  Only had mrxvt
running screen, but all terminal emulator tabs were sitting idle, and
also sometimes ran liferea and pidgin or irssi, pcmanfm at times, and
evince and epdfview at times, too.
