Package: iceweasel
Version: 24.2.0esr-1~bpo70+1
Severity: normal
Dear Maintainer,
I found that the 24esr version of iceweasel (linux debian 7.3 stable, x86-64
laptop, dual-core Intel Core2 duo) often causes 100% CPU utilization upon
resuming from sleep. I don't know which tab causes this though. I have a
suspicion that perhaps gmail is the cause (since I always have that open), but
I am not sure.
I have noticed that this issue also exists on the mainline version of firefox
(specifically, "aurora" branch up to version 27; perhaps v 28 also have it but
I don't know that for sure).
This is what typically happens:
- I close the laptop and it goes to sleep-to-RAM
- upon resuming, I notice the CPU being hot--and iceweasel uses 100% CPU. Also,
xorg uses about 50% CPU
- I tried to close tabs one by one, it did not cause the CPU usage to decrease
- nevertheless, iceweasel is still fully responding and functioning (but
somewhat slow, of course)
- I tried to close the program, the iceweasel GUI window(s) was closed, but at
the same time, the CPU utilization goes > 100% (i.e. all two cores were
occupied by iceweasel), often to ~200%.
- The only resort is to kill the process using "kill" command and restart
iceweasel.
- Comment: The last time I noticed this problem, the laptop was plugged on AC
before sleep, and was on battery upon resuming. Also I woke the laptop up in a
different building (thus, different wi-fi SSID).
Too bad that firefox/iceweasel does not have tab process viewer, akin to
“ps” that can show CPU utilization per thread. I imagine this is not too
hard to do for one who knows the code well.
This is a very annoying problem that I have noticed for many months. I decide
to report this, in case someone can help pinpoint the issue. I have not
restarted afresh with a blank profile (I have too much information deposited on
my current profile.)

Version: 115.12.0esr-1+rm
src:iceweasel has been superseded by src:firefox-esr in version
45.0esr-1 in March 2016. Transitional packages to ease upgrades were
provided in the wheezy, jessie, stretch and buster releases. The
transitional packages have been removed finally before the bullseye
release in August 2021.
After regular security support for buster ended in August 2022 and LTS
support ended in June 2024, I'm closing the remaining bug reports now.
