For the most part this extension works if you like backgrounds and other fun customize options. However, there are significant flaws. First off, for those that want the adblock function, it's subpar and easily detected by youtube, but that's an easy fix, just turn it off in the settings and use your normal. My issue is the lag and when opening videos the youtube ui vanishes (until I reload the page) and there's no setting on to cause that, again it appears when I reload. Otherwise I quite love it as it gives me the option to use my own images to make my web browsing experience really mine

i really wanted this to work, but after i click on a video, the only thing thats on the page is the video. no menu for the video, no suggested videos, no title, no comments, just the video on the background. it also makes youtube constantly give you anti-adblock warnings, which my other adblocks dont do, so whatever adblock this plugin uses is subpar and easily detectable by youtube.

Is Customizer YouTube™ Safe?

Risk impact
Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Customizer YouTube™ requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.
