After using Chrome for a decade and switching back to Firefox, one feature I missed was the ability to right-click and Go to [url] directly, for any selected text that vaguely resembles a URL.
I made Goto foo to approximately replicate Chrome's behavior in Firefox, but it would be nice if no extension were necessary.
I do the same
Another option i'm aware of is CTRL+C, T, V and enter (Keyboard combo to Copy, open new tab, paste, go)
