Bug Description

On my lapttop version 747 of the Firefox app is installed.

Whenever I try to launch /snap/bin/firefox I get a popup that Firefox is already running.

ps -aux does not show any such process.
Rebooting and deleting lock files in ~/.mozilla does not solve the problem.

Best regards

Heinrich

Removing the snap and reinstalling solved the issue for me. Still I wonder why it occurred first hand.

Could it be that you had an instance of the firefox deb (or another upstream build) running?
If so, firefox might be trying too hard to detect whether another instance is already running, but I suppose it's by design.

Good to know that you managed to resolve the issue anyway. I'll close this bug, feel free to re-open if it happens again. Thanks!

I have a similar issue (let me know if I should open a new bug): launching the firefox snap for the first time (ie. while it's not running) works fine. But, once it's running, any further invocation of firefox fails with the "Firefox is already running..." dialog - for example, clicking on a url in a terminal, or running `firefox https://example.com`.
