I’m on Fedora 40 Workstation (Wayland) and both Betterbird and LibreWolf take about 3-5 minutes to start. I got the error message:
Librewolf/Betterbird is already running, but is not responding. To use Librewolf/Betterbird, you must first close the existing Librewolf/Betterbid process, restart your device, or use a different profile.
I tried several solutions such as:
restarting my computer
clearing cache
uninstalling both Betterbird and LibreWolf
installing them as a flatpak
Launching them in safe mode
The other browser I’m currently using is called “Floorp” and it runs just fine.
How do I fix this ?
