One word :: fantastically !!!

Installed 2.0.8 on Firefox 58.0.2 64 bit on Mac and Windows and still no Download button nor option to Download by right clicking in the video window.

Works like a charm.

C'est la meilleure

PROS It works well with individual videos. The Download button is very visible
CONS Sometimes the button Donwload will not appear, like when you play a video part of a playlist in YouTube. It opens and extra window to see the video and then you have to right-click to download. Apparently it only works for 10 videos one after the other, and then continuosly will get corrupted files
