I'll check whether this happens with fresh 116 profile or not. One noticeable thing is that I get a lot of "Exception thrown at 0x0000004BC7ED689D in firefox.exe: 0xC000001D: Illegal Instruction." from wasm, I wonder this is related?

I'll check whether this happens with fresh 116 profile or not. (Edit: it does not)

One noticeable thing is that I get a lot of "Exception thrown at 0x0000004BC7ED689D in firefox.exe: 0xC000001D: Illegal Instruction." from wasm, I wonder this is related? (Edit: It happens on a fresh profile, so probably not)
