I just need to give it another chance, I literally removed Firefox two weeks ago after a problem using video calls, buuut I'm always fing around with the audio setup so Firefox may not have been at fault. For real though I never knew there is a Wayland mode, I'm excited to try it
Been using Firefox for over 15 years, including weird open source custom forks of it, and I've never run into that issue. I've got bookmarks kicking around that I imported into FF from IE on Windows XP.
Not saying it didn't happen, but I'd hazard a guess that it was related to some bookmarks related addon you installed, or user error. Sorry you lost your bookmarks.
