Missing Chrome's 'Go to URL' feature
(sh.itjust.works)
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.
You can also drag it to the tab bar to add it as a new tab.
