Dear Maintainer,

For some reason my `firefox-esr` is refusing to show me some pages.
Most pages work fine, but some give me the dreaded "Gah. Your tab just
crashed".

Two example URLs which suffer this fate are:

https://diro.umontreal.ca/accueil/
https://www.nserc-crsng.gc.ca/students-etudiants/ug-pc/usra-brpc_eng.asp

in both cases, if I `firefox-esr --safe-mode <URL>` it starts up and (after
confirming that I understand what "safe-mode" means), it gives me the "gah..."
instead of showing me the page.  On stdout/stderr I see:

    [Parent 18669, IPC I/O Parent] WARNING: process 18781 exited on signal 15:
file ./ipc/chromium/src/base/process_util_posix.cc:264

I tried `aptitude reinstall firefox-esr` but that made no difference.

I downloaded Mozilla's own `firefox-esr` and this one does *not* exhibit the
problem.
I also tried to `aptitude reinstall libnss3:i386 libnspr4:i386` which are
apparently the other packages containing the `.so` libs included in Mozilla's
own tarball, but that did not help.

I tried running `firefox-esr` under GDB but the error is apparently caught
internally because GDB did not show me anything beside loads of creation (and
exit) of threads and the same IPC I/O error message as quoted above.

I don't know how to track this down further :-(
