Firefox Windows Not Restoring to macOS Desktop Spaces

Firefox Windows Not Restoring to macOS Desktop Spaces

Firefox loses macOS Space assignments on relaunch because session restore recreates windows rather than resuming them. Workarounds: use All Desktops, avoid quitting, or use window manager layouts.

Firefox windows do not restore to their correct macOS desktop Spaces after quitting and relaunching. Root cause: Firefox uses session restore to recreate windows rather than truly resuming them, which loses the macOS Space assignments. Workarounds: - Assign Firefox to "All Desktops" in macOS dock options (windows appear on every Space) - Avoid full quits — use sleep or lock instead of quitting Firefox, so windows maintain their Space positions - Use a window manager like Rectangle Pro or Moom to save and restore window layouts including Space assignments - Create separate Firefox profiles for each desktop, launching each profile on its designated Space
