Not perfect, but damn close.
The user interface could use some refinement, it's slightly unclear, but decently functional once you learn how to use it.
It struggles with some sites, like Youtube, but does work for 95+% of sites. I haven't seen another addon get anywhere close to these numbers.

Ottimo strumento sia per svago che per studio

Excellent addon, the best one I found to quickly grab videos! Great work mig!

I love this mod, it works great. for anime and other sites. I easily would recommend this to anyone that loves downloading things to watch on their phones. Just know it dont work on twitter and some other sites but it works on many others

it's convince for me to download videos from webs.Excellent Add-Ones.

muy buena..

I have been using this add-on for years and it is my absolute favorite to capture and download videos! So easy, user-friendly, and quick. I absolutely love it.

I love this add-on. Where other video down loaders fail, this one works every time, for me.

Отлично работает! Качает и с Ютуба и других сервисов

It has worked as expected.

Simplesmente imbatível, o melhor de todos. Já me salvou de várias situações.

I just wanted to download a 30-second YT video - even after installing the helper app, it took 10 minutes to "aggregate" then informed me it had watermarked the video because I chose an "ADP" menu option (the only one available) and didn't register some conversion feature. A huge waste of time for even the simplest of uses.

Gran aplicación, muy intuitiva, muy util. Ideal para extraer videos de diferentes paginas web. Es mi add on favorito de Firefox

Muy util para descargar todo tipo archivos

Ist nur noch ein standard downloader

Has worked flawlessly for downloading videos thus far.

Great Addon, easy to use and usually no trouble recognizing the main video file.

I've used this for several years now, while i only use this to download videos, it does so very well, companion app is needed for certain sites, thx mig
