When I downloaded it the first time it worked well (a long time ago, talking about years ago).
Now the download speed is "meh".
If you download multiple videos (across many tabs), it will crash and it won't say which videos weren't downloaded (it only appears to report the bug).

It would be more helpfull if it wrote also the video titles where it failed so thwey can be downloaded again.

Great app, works well but a massive QR code is a bit excessive...

One is doing the right thing our of your own motivation, other is being extorted to do it.
Other than that, can't say much about the new version as I obviously didn't yet had the chance to try it.

Currently, I am unable to view some of the videos I have downloaded.

This add-on requires a secondary program for downloads, and it leaves a QR coded in the video that covers the bottom left-hand corner, taking up a quarter of the screen... permanently! Not a great look. Don't know how to remove it. Definitely distracting! Borderland unusable!

This is no doubt the best YT down loader. However for sometimes now is completely dead. Even after the last update 1.28.25 I cant download nor detect any video on YT.

Sporadic access to YouTube downloads but still good downloads from all other sites.

I have purchased the Gold Key, but I cannot download the 1080p video after 2 hours.
