Thanks to raingloom, we know that deleting some parts of the profile can work around the segfault. I set out to find the minimal part of my profile that I could delete while still working around the segfault. All I had to delete was the line user_pref("network.captive-portal-service.enabled", true); from ~/.mozilla/icecat/$my-profile/prefs.js. Methodology: I put my whole profile into a git repo, then deleted it file by file with for i in * ; do rm $i git commit -am "Remove $i" done then I used git bisect to find which file(s) had to be deleted before icecat wouldn't segfault. Once I had a set of files whose deletion avoided the segfault, I minimized that set by "un"deleting them by git reverting the commits that deleted them. Eventually I undeleted all the files in the set except prefs.js. I then bisected on the lines in prefs.js, this time manually. I found that the deletion of just the network.captive-portal-service.enabled pref is sufficient to avoid the segfault. I tested this with icecat 78.4.0-guix0-preview1. $ guix describe Generation 318 Nov 12 2020 07:36:51 (current) ... guix 07914de repository URL: https://git.savannah.gnu.org/git/guix.git branch: master commit: 07914def98ca0d148e3522466227304e45286786
