Bookmarks are not visible after starting Firefox

[DrFeelgood]

Firefox Version 138.0.1 (64-Bit), updated on May 5th 2025.

Firefox bug: It starts without opening the bookmarks. Although they have been customized as "always visible". It would be nice, if you could solve this problem. Thanks a lot, in advance   🙂

Same problem here, bookmarks panel does not open automatically after a restart.

Please fix this problem.

- under the Application Basics section next to Profile Folder, click the 'Open Folder' button

- close FF totally > delete the xulstore.json file in the profile folder > restart FF
