Easy to use and works on everything I need.

Been using this addon for over 4 years & no serious problems. Every once in a while, might come across a site where it doesn't work, but overall it's fast & reliable.

Excellent add-on. Very useful.

Extrêmement pratique et fonctionnel. je recommande ++++

Very nice powerful and wonderful soft. This is an important tool.

很方便、很好用，虽然有时候会有下载失败的情况但是瑕不掩瑜，给个五星好评！！！要是能支持直接下载哔哩哔哩上的视频就更好了。

El mejor ADD-ONS que tengo

One of the best ! Not perfect for hls files but very usefull ;-) Thanks to the dev team.

It doesn't work when you first install it, then tells you to download some other app, then still doesn't work - cannot detect any media playing. FAQ/support is snide and condescending. Plenty of other addons do this better, with no need to download anything, far better success downloading videos, and friendly support. Why is this recommended by mozilla?

is able to convert/download almost any stream/file. sometimes fails, but that might be because i didn't leave the stream playing. on a rare occasion, wasn't able to download a file, but that's RARE

Absolutely fantastic. Easy to use and works on everything I need it to. Thank you!

Very useful, I've downloaded a lot of files that I couldn't have accessed otherwise thanks to this add-on. :)

Functional and good use

Excellent tool! Thanks to the developers.

Simple, easy to use, does the job. Fantastic add-on.

Won't download most files without an external app, which isn't mentioned in description. After downloading and spending 30+ min converting, it then informs you it has put a QR code watermark on the video (again, not mentioned anywhere prior.) Complete bait and switch.

Very good product, easy to learn, many options for download. Works for quite a number of sites. Wish they allowed Paypal, I'd make a donation.
