Firefox stops loading webpages/playing videos after being open for around 4.5 hours

[SCFHG]

Hi all,

As of recently, since the last update, something peculiar happens when I have Firefox open for around 4.5 hours.

Webpages, and videos stop playing.

The fix: Fully close Firefox, and re-open. The issue goes away.

Anybody experienced this, and what is the permanent fix?

Firefox version: 150.0.1 (64-bit)

OS: Microsoft Windows 11 Pro

OS version: 10.0.26200 Build 26200

Regards

My videos will freeze (the whole tab locks up) and I'll have to close the tab and open a new one to either finish my video or start a new one.  Sometimes, I can leave the tab open after trying to play the video and it will be a good 8 hours later when it starts playing again (wakes me up and then I have to stop it which freezes it all over again).  It's a pain.  Chrome doesn't do it but I then have to deal with ads.  So I have to decide which I'm willing to deal with.  This last update I thought things were fixed but then it just now froze again.

Firefox - 152.0.1
