Seems to be crashing mainly on Late Beta starting in 109

Despite it being marked disabled, there are around 340 of these crashes on 109.0.1.

The bug is linked to a topcrash signature, which matches the following criterion:

• Top 20 desktop browser crashes on release (startup)

No crashes in 110, which is interesting. Fx109 is already past the point of any fixes happening, so we can probably close this out as WFM if 110+ continue to remain crash-free.

This is still the case, WFM.
