As per the topic, previous to Ubuntu 22.04, if I ran the command ‘firefox’ and firefox was already running, it would open a new window.
As of Ubuntu 22.04, if I run ‘firefox’ and it is already running, I get ‘Firefox is already running, but is not responding. To use firefox, you must first close the existing Firefox process, restart your device or use a different profile.’ - Firefox is working fine, so it appears snap is not connecting to the existing instance.
How can I fix?
