MacOS: Freezing when waking from sleep

[plz12345]

What happened?

I'm using Waterfox with 2 profiles to isolate browsing.

About 1 in 3 times I wake my Mac from sleep, the browser will completely freeze on both profile instances, requiring it to be quit and restarted. This just started happening within the last update or two.

I will note, I don't have to force quit the instances, so they are at least responsive to a normal quit via ⌘+Q.

I've tried reinstalling already.

Reproducible?

• [ ] I have checked that this issue cannot be reproduced on Mozilla Firefox.

Version

6.6.5.1 (aarch64)

What platform are you seeing the problem on?
