It used to work great for any playlist but now it only works for the Playlist "Watch Later" and "Liked Videos".

Update: The problem was fixed and now its works perfectly. Great extension.

Works perfectly. It also has a sorting feature.

It is exactly what I was searching for - these options for sorting are amazing!

Mozilla Firefox 129.0 (64-bit) — OK. Please add playlist duration to search results (youtube.com/results?search_query=... pages).

It works perfectly and integrates seamlessly into the page. You couldn't ask for more.

Inconsistent behavior. For longer playlists up to 50 videos or more the plugin doesn't work properly, sometimes it calculates a integer number, and whether you refresh the page the new calculated number isn't equal to the previously one.

It works so well. Also looks beautiful.

Please make that the percentage of the player is displayed

It worked before,(but youtube changed it's UI so they broke it). I saw that the extension's code is being updated on github, which means an update will hopefully come soon, so anybody looking to the reviews wondering why it does not work, just have a little patience.

Just does not work for me. :-(

Why it's not native YouTube feature?!

does not reliably update the calculation of the playlists

5 stars because it show the duration and the number of videos that calculated(Loaded) and when the page scroll down(load more videos in playlist) it recalculate the duration and update it with the number of videos loaded to be sure the all videos calculated, thx
