I have a shell script that opens several tabs in default browser for 2fa process (indirectly by using aws sso login). This script runs in WSL2/Ubuntu 22.04.
Now this is interesting: The behavior is always same, like it would run by default in no-remote mode: first tab opens fine, all the subsequent will fail with "Firefox is already running but is not responding...". Seems second call to firefox is always launching a new instance instead of connecting to existing one. The same happens if I'll try to just start firefox twice from console while it is already running. If I use different profiles then it works. It behaves same as in here except the fact that $MOZ_NO_REMOTE is not set at all.
Things already checked:
$MOZ_NO_REMOTEis not set, not zero, not empty string, just not set- deleted
~/.mozilla/firefox, it created a fresh profile but still same behavior immediately as soon as second link is opened. - after closing firefox there are no zombies left
- there is only one firefox installation in Ubuntu in
/usr/bin/firefoxusing apt - This was fine several months ago (many wsl2 and Ubuntu updates ago)
Update: experimented a bit and if I launch firefox as superuser then this works as expected, I will get two tabs/windows with a single pid
