I am using Guix on Icecat on version 102 and its still persistant. Do
you have issues with it keeping the captive portals setting off, but
upgrading to a new version while still segfaulting. I would just keep it
off for now. Cause as long as it doesnt break after upgrading, at least
(for me) its not totally experience ruining.

Anyways, sorry for the lack of real solutions ☹️. But i'll do some
testing to see what if at least it doesnt break on upgrade.

Stay well,
