Profile Switching shows userChrome File changes quickly ?

[SheepDomination]

Upon adding a rule to my userChrome file within a profile, When I switch between two different profiles in Zen the profile which the rule is applied in the userChrome file I see the changes for a quick second, then changes back ?

This behavior is likely due to instability in Zen's new profile management system, which has been undergoing major changes and is still in development. There are known issues with profile isolation and persistence, especially after the removal of the old profile switcher and the move to a new SQLite-based system. These changes can cause unpredictable results, like customizations from userChrome briefly appearing and then reverting when switching profiles—this is not expected behavior and has been reported in the context of other profile-related bugs as well [source][source].

For now, make sure you're using the latest version of Zen, switch profiles using about:profiles, avoid rapid switching, and back up your profiles before making changes. If you want to troubleshoot further, try testing with a fresh profile and minimal userChrome changes, and check for any errors in logs or config files. The profile system is still evolving, so keeping an eye out for updates or hotfixes is a good idea.
