I like it. I purchased the original IDM license and use it everyday. Altough I must say that the firefox extension one does not have the ability to download on click only (the extension is always on) which bothers me because sometimes it does not catch the download link and just doesnt appear at all.

The download panel suddenly disappeared from Youtube yesterday.

download panel not showing at YouTube

In version 6.42.18.3 (or earlier), IDM is not able to detect media streams on sites if Firefox is run with the -wait-for-browser switch.

Good performance...nice

Currently the best browser to use this on seems to be Firefox thanks to chromium or more or less Google enforcing manifest the three and other things like that soon Firefox will be the only way you will be able to keep the media you want
