I just went through a long list of keyboard shortcuts for Firefox. One that I didn’t see that I would find useful is to press something like ⇧ Shift + ⌘ + C to copy the URL and then paste it into an email or message to send to someone. Does something like this exist?
I do ⌘ + L to move focus to the url bar then ⌘ + C to copy
edit: apparently others have already said this and those comments just haven’t gotten to my server yet
