Hi, Mark!

I have not used IceCat 102 myself, but the user that reported this 
claimed they were using 102.3esr.  I pulled the user agent string from 
nginx logs from a jitsi-meet instance so some people are using it in the 
wild.

I made a server-side change to correct IceCat to Firefox on the server 
side and asked them to try again [1].  The single change did not fix the 
issue, but after the user claims that the page worked after they 
disabling privacy.resistFingerprinting.
