I think this is the same as bug 1713973.
Looks like this is a profile with the experiment enabled then being used on Release Firefox, where we don't have the work-around from bug 1696940.

nope i updated to version 90 and tried win32k lockdown, i always want to try new experimental features of release versions like fission etc...
i reported to know if it is an easy fix by the firefox team or more complex than that and i do want it to be working better in future releases as well that is all.

Ah, so you set it via the pref, sorry I thought you had set it via the Nightly Experiments page.
Either way thanks for testing this, like I said in bug 1713973, we should probably remove / disable this pref apart from in Nightly with this known quite common crasher.

no worries, and thanks hope it will be crashless in the future.
