It worked fine until the last update. Now, this thing slows Firefox down to a crawl, eats >95% of my available RAM, and it is impossible to access the menu even after reinstalling it or restarting Firefox, before memory usage blasts through the roof, because the menu won't even show up.

Clearly, as many other users have said, the devs should revert to the previous version and leave it at that, because it was nice, unobtrusive and did the job as asked. We don't need no fancy stuff or whatever, just tell me what videos are on the current tab (limit the displayed list to 5 or 10 items if there's a lot of videos, with a link to open a complete list if needed, which should hardly ever be needed), allow me to select which ones I want to download and where, and that's it.

I'll keep an eye here to see if the devs come back to their senses, but I'm also going to look for other apps doing the same job. If I find a good one, I'm probably not coming back though. Too bad, this extensions had been awesome for many years, but not anymore.
