Many thanks for this. Paste and go via keyboard shortcut is way more useful than via the context menu version. I'm surprised it's not native to the browser like in Opera and Vivaldi.

Firefox, and any other browser for that matter, would be much less functional without it.

Not working if dom.event.clipboardevents.enabled is disabled.

It would be nice to have a second icon for search like the old pastego:
