In the meantime, to start IceCat 78 with your existing profile but with addons temporarily disabled, try running: icecat -safe-mode That should allow you to recover your existing bookmarks, history, cookies, saved passwords, tabs, etc. Then you can try adding back your preferred addons incrementally to find out which one is causing the problem. > Tbh this would be a good time to have a debug output for IceCat on hand. While I acknowledge that it might occasionally be useful in edge cases like this, it would also dramatically increase the memory requirements at build time. For what it's worth, in the ~6 years that I've been maintaining the IceCat package in Guix, I don't recall being asked for a debug output before now. I'm particularly sensitive to the memory requirements at build time, because I choose not to trust the build farm and therefore to build my entire Guix system with GNOME from source code on a relatively old Thinkpad X200 with only 4 GB of RAM. I've been doing this for many years, and I'd like to enable other Guix users to do so if they wish. My impression is that IceCat debug outputs would primarily useful to people who are actively developing IceCat, in which case it makes more sense to build it manually to allow incremental rebuilds after modifying the source code. If it turns out that there's more interest in IceCat debug outputs than I've anticipated (others: please speak up if you need this!), I'm not necessarily opposed to adding them, but someone with a more powerful machine would need to take over maintenance of our IceCat package, because I would be unable to locally test the official build. What do you think? Do other people need IceCat 'debug' outputs? Thanks, Mark
