I can confirm it's a Snap issue. The problem is that's how Distros are providing FF pre-installed and it needs to stop. I'm still using FF 102.0 because I disabled Snap updates. Works fine, but it's exactly what causes security issues. When you do so...
Bad enough it updates itself without asking. Fine. STOP expecting me to restart it for no reason. It's working fine. It'll restart when the PC does. Until then, leave me the hell alone. You have no business breaking tabs and forcing a restart.
