Package: firefox-esr

Severity: important

I’ve basically copied my Firefox profile from a Thinkpad X61 with bullseye
to a Tuxedo AMD Ryzen 7 8845HS with trixie.

I experience somewhat-reproducible Firefox freezes: first, the tab, but
after a while, the entire browser freezes and needs “pkill firefox”.

I have recently found a trigger for this: go to https://bahn.business/,
(always wait a bit until the pages have fully loaded here),
then click in the upper-right corner on Anmelden, then go to the eMail
field if you even can, try to enter a valid address, submit, and by now
it should be hanging. Sometimes, it involves Ctrl-T and loading e.g.
Wikipedia, then switching between the tabs for a bit. If you have an
actual DB account, try actually logging in, then go to your saved trips,
that is the latest crashpoint for me atm.

I’ve taken some time to debug this today:

- ff -ProfileManager
- create a fresh empty profile
- exit Firefox
- overwrite prefs.js
- start that otherwise new, empty profile
- try the reproducer

I was indeed able to trigger this crash with just *one* setting:

user_pref("media.autoplay.blocking_policy", 2);

I then exited Firefox, removed just that one line from the prefs.js
of my production profile, started that, and can now log in, see my
bookings, etc. all without a hang.

This might also be a regression. Should I test with older releases?
Can you reproduce this?

(This might be time-critical. The Deutsche Bahn website might have
changed something to trigger the crash more reproducibly, recently.)
