I used to defend the developper of this module against criticism about issues, because I know that YouTube constantly modifies its code to prevent downloading.
However since a few months this add-on never worked correctly and the support answers didn't satisfy me at all (well, mainly because they never answered my last message).
I sincerely hope it will get better in a near future but I fear it won't really

This dowloader worked great early on, but later and as of now it doesn't finish downloads and just hangs up even on the smallest ones.

Will make videos stop playing after 2 seconds in the video. Pure 1990's angelfire vibe to it.

Pushing pro-subscription for 1080p videos it's a terrible way to promote you extension. Ask pro subscription for something worthy of such as 4k or 8k videos options. Otherwise, better to look for alternative extensions or webpages.

Since the latest update, the extension has failed to download any long Youtube videos. For the shorter videos, the download speed has decreased.

You have to pay for anything useful to work, the reason makes sense, so not 1 star.
Also im noticing what looks like lots of bot 5 star reviews???...
The UI is pretty nice, so I would have used it more if it ... worked, ya know.

keeps showing nonsense notification when i don't even want download anything.annoying

used to be good, but now it needs a "PRO" version to download anything with a decent quality

If you want to download HD it asks you to pay for this. No way, I deleted this add-on right away.

The addon works well, but the "One time payment" claim is false. I've been asked 3 times in 3 years to donate as he removed my access. Should be more straightforward if he wants yearly donations instead of claiming a lifetime payment.

"Offers" 1080p downloads. As long as you pay them.

It actually is very easy to use, but sadly the downloaded video has significantly worse quality (everything clearly gets blurry) and it displays as lower frames per second than the actual video. 60 fps gaming video looks like it turns into 40'ish fps.... Not worth it to get a laggy crap quality video.

the new popup on the right when i watch a live stream sucks ....

2 stars because it works but has invasive pop-ups that force a tab switch.

Download button disabled suddenly without any action on my part save for refreshing youtube webpage
