[12.04] latest firefox ( 11.0~b2+build1-0) is always producing 100% cpu usage

[Michael Basse]

firefox is producing 100% cpu load, surfing in the web is impossible with that situation

calling firefox from the shell did not show usefull debug-infos

strace should a loop with this

Happens here randomly in the middle of web browsing.
It then completely stucks, either needs to be killed or reloading all tabs may help.

[Michael Basse (michael-alpha-unix)]

still happening with the new version 11.0~b2+build1

i will open an upstreambug for that and link it here in the bug-watcher later today

[Michael Basse (michael-alpha-unix)]

after some debug-sessions i found out that an addon is causing the issue with the latest firefox-beta. Because of that i will close this bug as invalid because its not a problem with firefox itself

[Michael Basse (michael-alpha-unix)]

just for the record, The issue was caused by the sabnzbplusd addon. My sabnzbplusd was crashed but the firefox-addon was trying to contact the server every second. Thats waht the strace is telling from #1.
