Has not been updated in over a year according to the changelogs. The settings to revert to old layouts don't work properly on the recent layout YT is rolling out (the one with comments/description on the side).

Upon using the default settings, the entire home screen proceeded to shake up and down resulting in a strobing effect. While this goes away upon scrolling, any time I returned to the top of the screen, the strobing would happen again. This occurred with the Current, 2017, 2016, 2015 and 2014 layouts, of which the 2017 is the default.
Additionally, "Restore Youtube Dislike compatibility" does not do anything. Despite reloading the tab and verifying that the extension is still on, dislikes are still hidden, regardless of this option being selected or not.

UNFORTUNATELY, THIS ADD-ON IS PERCEIVED AS AN AD-BLOCKER BY YouTube

I've used this nice add-on for 2 or 3 years, especially the volume boost feature.

But as of 2023/11/9, I was always met with a black screen on YouTube, which left me quite puzzled.

I examined the add-ons, and reached a conclusion that the cause of the issue is this "YouTube Enhancer".

So, I disabled it by the Firefox Add-on Manager, and was able to resolve the issue.

Dear developer,
I hope you could fix the problem if possible.

Глючное расширение, главная страница ютуба в области роликов начинает мерцать и дергаться.

I like this extension as it can change the main page of YouTube to remove the Shorts area (which I don't use and it just gets in the way). It's weird that the extension is called CustomTube but in the the FireFox Extension website it's called YouTube Enhancer...
