Pretty busted piece of software. Half the media are "Not found on Trakt", even though they're very much on Trakt and tagged perfectly there, and out of those that are found most don't get scrobbled automatically for whatever reason–I keep having to do it manually by clicking the sliders on the History page.

Sadly doesn't work on FF 72+. Icon doesn't show, so I can't login to Trakt.
Works fine in Chrome, though.
