Rated 4 out of 5 stars

It's very great, making everything practically perfect when you want to download a movie, multi files or with download manager.
It might work great with Free Download Manager, but it takes very long to start it. Starting it manually makes it work immediately though. Sometimes it doesn't start FDM at all just waiting when I start it manually :/.

The second problem is that in media list displays files without size or size very small e.g. 48B (bites). They're not certainly media files, so could you just give an option to not detect such (small and unnecessary) files.
It could be nice also if toolbarbutton wouldn't just vanish when not active, just grayed or something, but still allowing to access settings command for example. You could give an option to choose if it would vanish or not.

This review is for a previous version of the add-on (1.5.6.12.1-signed).
