    @Harper-ReinstateMonica sorry you're right, Google would never tell me how to change YouTube's default settings. Mar 31, 2020 at 6:56

On desktop browsers one way to block this is using the uBlock origin extension. Right click after installing it, and select "block element". The element you want to block is:

###clarify-box > .ytd-watch-flexy.style-scope

From your screenshot, it seems you are browsing youtube using the chrome web-browser, but with "Desktop site" enabled, is that right? If you turn that off it should not be displayed


On Firefox on Windows 10, you can do this without installing any plugins. In this folder,

C:\Users\<your Windows login username>\AppData\Roaming\Mozilla\Firefox\Profiles\chrome\

create a folder named "chrome". Inside this folder, create a file with the name userChrome.css. Add this to it:

#clarify-box > .ytd-watch-flexy.style-scope {
    display: none;

This technique allows you to modify the css of any part of any site, not just YouTube.


As a complement to oaeide's answer, one can use oaeide's code with Adblock Plus Chrome extension:

  • @mbomb007 Oh, I use Firefox. But "anyone who has ever […] opened the settings once" is probably just over half of ABP users… hmm… Actually, ABP does make it much clearer than I thought it did.

Very easy way. I did it on Firefox and Brave. The banner has several parts. For Brave: Right click on Covid 19 banner. On pop-up point to Brave (or your adblocker installed) - Block element via selector - on new pop-up click OK. Repeat it for each part. For Firefox you need uBlock Origin installed. Right click on Covid 19 banner. On pop-up point to uBlock Origin icon. On next pop-up click Create. Repeat it for each part.
