Please fix it for newest Firefox in August 2024 i hope have new update soon.

Broken sometimes, especially likes and dislikes icons

At first It was a stellar add-on. It did take time to fix YouTube after it's UI drank a gallon of lead paint and died...And then suddenly It just stopped working, the main site was alright but the videos were back to their heinous new look and I have seemingly no way to change it. Hopefully this or Youtube gets their shit together otherwise I'll have to quit that venue alltogether

I actually like this add-on a LOT because it brings back the old YouTube from like 2015. It gives me so much nostalgia on how much I used to watch videos back then on these old computers with Windows XP, 7, and 8.1 on them. But after time passes, YouTube has new designs.

But, this add-on has so much bugs. Such as the video player having the settings inaccessible (the only way you can access it is by pressing T to bring up theater mode which allows you to bring up settings and other things) and also playing back video when I clicked off it.

It also keeps skipping on playlists most of the time, which annoys me and bugs me. So, if these bugs were fixed, I will give this a higher rating. Thank you!

Love the idea and it does work but it also seems to disbale all my other youtube add-ons such as the download button

Well,
I gave a try to this extension, hoping to have the good experience of
old YouTube.
However, other than some visual changes, i didn't noticed a difference
in performance. YouTube still sucks the same..
Slow loading with high cpu & memory rates, 2-3 sec to go full screen
and vice versa, showing black during this transition, etc etc..
There is also something very irritating: it doesn't retain its settings. If i
close all YT pages and later on i go again on a YT page, i find all settings
to have been reset to defaults.
I'm afraid we have to say bye bye to old, good YouTube. For ever..
The exact same as new Facebook.
It looks like they compete each other, which one of the 2 will be the worst..
