You open a new tab
You toggle the "edit needed flag"
Latest docker version.
EDIT: Firefox, Chrome, Edge and Internet Explorer (and possible other browsers) all use CTRL+T for "open new tab". I don't understand how "Changed in version 2.18: The keyboard shortcuts have been changed in 2.18 to less likely collide with browser or system ones." led to CTRL+T as a viable shortcut.
Apparently we need something better here...
Any suggestions for good shortcut?
From the top of my head: Is CTRL+Q used anywhere?
Quit Firefox? Doesn't sound like a good option...
I use Firefox on a German Windows 10 Pro. CTRL+Q doesn't do anything for me. Is it language-specific?
The German Firefox documentation says CTRL+SHIFT+Q is close Firefox...
Same for the English docs:

On Linux the default is Ctrl+Q.
Thank you for your report, the issue you have reported has just been fixed.
@nijel Thanks for fixing this. Is it possible to donate via crypto and get a receipt for the donation?
Sorry, I currently can't issue receipts for crypto donations.
