This was simply the best and easiest direct downloader for YouTube, thanks to the pop up menu showing all available formats.
Regarding slow speed, this is coming server side from YouTube... ANY utility will have the same speed restrictions. Looks like they are throttling their bandwidth so nothing plays faster than it would for streaming... understandable; the amount of bandwidth they use must be staggering.
Sadly, it looks like this legacy add-on finally stopped working all together recently, as it will no longer download anything. The pop-up window showing all available formats is still working and useful however.
I would encourage the author to come back... web extensions isn't really needed as there are several XUL forks of Firefox now that people are using that this add-on in its current form can still work on... Pale Moon, Basilisk, and Waterfox, for example.
