Yep , it greyed also in my browser. It could be really better if we would download other's playlists too. any kind of playlists

Doesn't work at all, after it scanned, I clicked download then it greyed out the button and says Downloading... But nothings happening, I left my PC running for 3 hours thinking it would be finished by then but it didn't.

doesnt download everything, skips heaps actually, still good attempt

It's a very good extensions, easy to use and with a great interface. I've only encountered one error: sometimes it doesn't recognize the workflow folder it downloaded previously. Maybe the reason is that I later added a new song to that folder, then removed it, or deleted the song. The folder is still there, but it thinks it didn't download that folder.

Would be neat with the latest version on FF as on Chrome to fix the memory problem. Besides that, this addon is almost perfect. Remembering last settings between sessions (the parts to download) would be useful. When downloading everything, it seems to download in the root folder, it should be in Workspace folders if marked. So up till now, very useful, until it kills the browser because of the memory bug. So thanks for that.

Once you hit "scan" it slows down Firefox to an absolute crawl (clicks take very long to register) for at least a quarter hour before eventually crashing it totally. Restarting Firefox & then hitting "scan" in the extension, again froze Firefox.

Ok, i was in the middle of writing my own extensiont, but got damn this slaps.
Works slower than mine, but scraps everything that i need, without struggle.
