AVOID
1. The app forces you to download an outside program before you can use it at all.
2. The videos have big, distracting QR codes in the corners.
3. Downloads were very slow and videos were sideways for no reason.

Firefox seriously needs to review the quality of this app and take down all of the fake reviews.

Works really well for capturing streamed files

It works great and I am able to download all the videos I want. I also love the UX. A great experience using it!
