User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:109.0) Gecko/20100101 Firefox/109.0

Steps to reproduce:

Start Firefox with the following tab open (from last session):
https://meinwebserver.non3dd1yd61r0h6y.myfritz.net/memLeak/index.html
or try:
https://meinwebserver.non3dd1yd61r0h6y.myfritz.net/

Warning: only occurs sometimes, and I don't exactly know under which circumstances. When it happens, you have to kill the tab process in Task Manager to stop loading the page!

Actual results:

CPU usage goes to 100%.
Computer RAM fills until none is left (or swaps out.)

Expected results:

The site is expected to load like any other page as it did before and normally does.

I've marked comment 2 as "obsolete" but that's just to collapse down the contents of about:support to make the bug a bit more wieldy.

memory-report.json.gz First memory measurement. Couldn't upload two files in report directly.

This is only the first dozen or so characters of a report so I'm marking it obsolete.
