Works well. Only problem is that it causes the entire youtube page to refresh whenever you click on a tab with the sort by oldest button.

It took only a couple of seconds to sort 5 years of videos on a channel so I could see the oldest first (much quicker than scrolling through page after page, thank you!!!)

However when I went back to that page of videos after watching a video, it was flashing and unuseable, so I'd have to refresh it and sort the videos again.

Work-around: Right-click on a video and choose Open in a New Tab.

Works perfectly :D

Just got it, and first impression is that this is perfect. Seamless and quickly goes through the oldest videos the way YouTube should've done from the beginning. Combined with a multi select extension and I can even create a massive playlist so that I can easily go through all of a creators hard work.

Works as good as possible, may take a minute to load the channel's videos but I'd imagine that's as good as it goes. (I too made an account just to rate this extension👌)

Works perfectly.

Made a firefox account just to rate this 5/5
