Hi list,

Since one week ago I'm noticing firefox is sometimes irresponsible during three or four seconds.

First I experiment it with swiftfox, then I used Firefox (iceweasel) 2 and the problem didn't go out. Then I switch to iceweasel 3 from experimental, and I see this again.


I don't know how can I debug this problem. iceweasel take high % cpu during the time it is irresponsible.

If I exec strace I get:
ioctl(3, FIONREAD, [0])**************** = 0
gettimeofday({1210772361, 739127}, NULL) = 0

poll([{fd=4, events=POLLIN}, {fd=3, events=POLLIN}, {fd=8, events=POLLIN|POLLPRI}, {fd=11, events=POLLIN|POLLPRI}, {fd=12, events=POLLIN|POLLPRI}, {fd=13, events=POLLIN|POLLPRI}, {fd=17, events=POLLIN}, {fd=10, events=POLLIN|POLLPRI}, {fd=48, events=POLLIN}, {fd=28, events=POLLIN}, {fd=18, events=POLLIN}], 11, 0) = 0

gettimeofday({1210772361, 739254}, NULL) = 0
gettimeofday({1210772361, 739295}, NULL) = 0
ioctl(3, FIONREAD, [0])
...

But I think this strace doesn't give any clue.

Somebody with the same problem ? Any workarround ?


I didn't install any plugin recently (only tamper data and developer extension installed on my iceweasel)

Thanks you !

Debian Rocks !
