Great when it works. But downloads frequently stall and must be manually restarted, repeatedly, to complete download of a large file. Auto-resume would be a nice feature to add if possible.

mp3 isn't working due to a change by youtube?

Apparently it does not work for MP3 files. Maybe youTube changed something. It works fine for videos, so I'll keep it. Thanks!

Unfortunately it not longer offers to download the 1080p HD videos without some pro account...

Great add-on normally, i lowered my score slightly because with the latest update, the ability to rename the video before saving is gone: no pop-up dialog box appears when pressing the button

It works, but practically only for 720p video. Does the job if you really want a downloader browser extension, but it's really limiting otherwise. I'm not bothered that mp3 is limited to a paid feature, it's easy enough to convert video files to audio only. What does bother me is the lack of 1080p or higher downloads.
Their excuse about needing "powerful server infrastructure" for 1080p+ downloads is a weird one, considering this is all done locally. You could convert to mp3 locally as well, but that's whatever.

All in all, it works. But you're better off just using software that lets you download as you please.

If there is an emoji(Segoe UI Emoji) in the page title, it cannot be saved. ex) https://youtu.be/PvA2oozgpxo

Wouldve kept but need to pay to download mp3

Over the past 3 or 4 weeks a lot of videos WILL NOT download in 720p and keep failing. only allowing you to download in 360, despite 720p and higher being available options. Other than this annoyance good add-on overall, but could be great.
Please fix

This is great for downloading videos, but the MP3 functionality has been broken by a change in the way YT handles the audio ... since 2018, five years ago. Developer should remove that feature as upgrading it would be unwielding.

Shame I can't save just the audio as an mp3 in standard definition and not high but works otherwise like it says it does.
Oh, also, it doesn't work on age-restricted videos? I can watch them because I'm not on an age restricted account or anything but I there is no download button.

You have to buy the Pro version for downloading Mp3,3GP and 1080p but I was able to download 360p with the basic add-on so it did partly meet my need.
