works on most sites... and works better than any other.

Bait and switch. Offers downloads but any video downloaded is transparently converted, significantly lowering the bitrate while also watermarking the stream with a QR code. This code linking a site where visitors are prompted to purchase a license for the 'converter' to remove the watermark. A mark that wouldn't exist if the 'downloader' just downloaded the source without superfluous conversion. It's deceptive, invisibly inserting itself into the media in an effort to trick the gullible into believing they need a license that would, if the media wasn't converted in the first place, be unnecessary. Not to mention it appears they've got some sort of bot service periodically five-star reviewing the extension presumably to bury negative reviews.

GOOD

You have to pay for an open source converter, or it will encode a large Qr code into the result with poor quality. So here you need an extra program just to be able to collect for this program. This is not what you expect, you want to download the stream without manipulating the stream.

I struggled with it at the beginning. Downloads were imcomplete aborted. Once I increased the timeouts significantly and reduced the number of parallel downloads everything was working nice. If you have trouble with this Plug-In have a look at its Behaviour preferences.

This app worked perfectly for ONE month. Then never worked again. It is worthless and I suggest not wasting time with it.

a very good video downloader with many download option and convert option.

Very nice and cool.

This was brilliant in the early days, then went through some changes due to FF changing. It is now back to being excellent. The queuing of files and limiting downloads helps a lot, the speed is generally good. The only issue I now have is, if you download several videos, then wish to cancel them, you have to do it item by item. Needs to be a way to select more than one and abort. Simple to use and to set up.

Essential bit of Kit for browsing experience. Excellent app in all respects.

Ótima extensão. Grata.

Nice Keep up the good work

Although it doesn't download all sites it's still the best in my humble opinion of all the "Extension" Downloaders in that it seems to work on between 92-95% of times I've successfully attempted to use it. Thanks
