Expected Behavior

Safri doesn't crash

Actual Behavior

Safari crashes

Additional Information

The crash is not reproducible, it happens randomly after some time (could be 5 minutes, could be 1 hour, etc..) The culprit seems to be the Advanced Blocking extension. If I disable that one Safari doesn't crash. The crash report doesn't actually give useful information, since the crashing thread is the main one, every time with a different stack trace.

Here's also a thread in the apple stack exchange with people reporting the same issue. https://apple.stackexchange.com/questions/410121/safari-keeps-crashing-after-updating-to-big-sur-termination-reason-namespace-a and one from the apple forums https://discussions.apple.com/thread/252054569

Yes, yes, yes! I second everything Choco describes with a long list of these random crashes while it seems AdGuard may be the reason.

Tbh, I am not sure what we can do with this. In the linked threads I see different extensions said to be causing it, not just content blockers.
