Hello, I'm currently running firefox developer edition and i'm facing a weird bug: When firefox is started, opening a web url from outside of firefox window does'nt work and display error message: "Firefox is already running but is not responding...". It expects that i close all instance of firefox instead of just opening url in a new tab. Do you have any idea? I'm working on version 105.0b2 with two profiles on an ubuntu 22 Thanks a lot for your help !

When firefox is started, opening a web url from outside of firefox

How are you opening a web url from outside of firefox? Provide the steps to replicate your issue.

From any other app containing url (vscode, discord...) with a simple click on url

Are you using the -no-remote command line switch to launch Firefox as that is a possible cause ?

@cor-el Thank you for your help! I actually used the -no-remote. Remove this option solves the problem.
