Very generic. does a lot of videos that other addons cannot do

Very good

Not works for youtube

Maybe don't advertise that you can download YouTube videos if there's a big red box that says you can't due to legal concerns.

I've been using Video Downloader Professional for years and it always does a fantastic job downloading videos I've needed. It's definitely a high quality app one can count on to deliver.

Works on most sites, but not all. However, is one site where it is the only add-on I've found that will download 1080p and higher versions of videos. Blocked in other add-ons. Also periodically stops working and asks to buy more advanced video software. I did this and found that software didn't work anyplace that the free version doesn't work and is more cumbersome to use. Once the promo for the advanced video shows up have to uninstall and reinstall to use. Sometimes hs just disappeared and needed to reinstall, really for that one site.

That said it is reasonably fast. One other issue is you have to know how many videos you can safely queue as rather than downloading one-by-one or some other number downloads will sometimes fail midstream if too heavy a load and sometimes can resume, sometimes not.

Yes

you want my shekels with some sort of pro version?
naw.
that aint happening, sport.

When it works it works pretty well. Faster than most Video downloader Extensions I have used. But it is vanilla. Vanilla in the sense that it won't work in places that don't want it to work. Websites that have video formats out of its scope will make it look lame. There are extensions out there that have a workaround. Works like 55% of the time tho.

Doesn't work on YT if that's what you're looking for.
