I just double click my firefox tabs to close them.
? doesn't work on my FF... is this a custom setting?
Oh I guess I must have one of those fancy add-ons or extensions installed for it
I prefer Double Click to Reload (also, ever see this one?
https://addons.mozilla.org/en-US/firefox/addon/text-link/h ). That is, until I learned of VimFx, where I can just press r... and x to close, and X to reopen.
But for you out there who don't know:
Ctrl+r - reload
Ctrl+shift+r - reload cache
Ctrl+t - new tab
Ctrl+shift+t - reopen closed tab
Ctrl+w - close tab
Ctrl+l - focus on address bar
Ctrl+k - focus on search bar
Ctrl+tab and Ctrl+shift+tab - move in between tabs
