Dear maintainers,
visiting [0] and pressing Ctrl + + three times in a row reliably crashes
iceweasel. Attached you'll find a backtrace of this issue.

The crash also happens in safe-mode from which I've attached the GDB
backtrace and register dump. The crash also happens with a vanilla amd64
build from upstream (I've tested their 29.0.1). I triggered the crash
reporter, but I don't see the report yet on the crash stats page. Anyway
it should show up in the reports tab of [1], which already contains some
other reports, including at least three, that seem to happen on nybooks.com.

Let me know, if you need something else.

Kind regards,
Kai Wasserbäch

thanks

Considering the low number of reports, and the fact that i can't
reproduce, I'm tempted to say this is *very* environment/hardware related.

Downgrading severity accordingly.

src:iceweasel has been superseded by src:firefox-esr in version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.
