[Bug] 4.0.15 hangs on ESR

[DarthGandalf]

Abstract

Since today TST is unusable on FF ESR 115.10.0 on Linux 64bit. It uses 400% CPU, and is either very slow, or just never successfully loads anymore, instead keeping blinking between showing progress bar and not showing. I tried to restart firefox several times, that's how having different results.

I see this in browser console

I downgraded to 4.0.14 for now, and it works fine.

Steps to reproduce

1. Have >1000 tabs
2. Do nothing
3. Let TST extension automatically update to 4.0.15
