Broken, at least on my latest version of FF. I see another review from 7 months ago say they disabled all content blockers and it still didn't work. I won't disable blockers on Twitter so if that's the reason why I'll never know. Too bad, would have been a useful tool.
this did not work for me on Firefox twitter for web. I disabled my other extensions (privacy badger & adblock) to see if they were interfering, but that was not the case.
