On Youtube you can activate the dark mode, which is really convenient for a video site. While reading on the PC is better done on a black text on a white background, different is the case of watching videos and films, which is certainly better if the screen around is dark instead of clear, especially if you use Youtube in the evening or night.
On Youtube you can immediately activate this dark mode, without using extensions, which is currently a hidden option, still in the testing phase.
To see the black Youtube background, just click on the button at the top right with three dots (or the face of the profile in case you have logged in with your personal account).
From the menu you can then move the switch that activates the night theme, with a black background, in Youtube.
If the dark mode option does not appear in the menu, do this:
Open the Youtube site and enter developer mode on Chrome and Firefox
The developer tools can be seen by going to the browser settings (from the menu at the top right, press on the three dots, then go to Other tools ) or by pressing the CTRL - Shift - I keys together.
In developer mode, navigate, if not already done, to the Console tab.
Note that at the bottom you can write, then click on the writing field under the Console and paste the following command:
document.cookie = "VISITOR_INFO1_LIVE = fPQ4jCL6EiE"
Press Enter.
As an answer, "VISITOR_INFO1_LIVE = fPQ4jCL6EiE" should appear.
Now, close the developer tools, refresh the Youtube page by reloading it and note that it should look a little different than before.
Click on the icon of your profile at the top right (you must be logged in to the Google account) and find, on the menu that appears, the option of the dark mode only to be activated.
The dark mode, after this activation, disappears if you close the browser and reopen.
If you want to keep this dark mode on Youtube and permanently use the new interface with the black background (which Youtube will still activate for everyone in the next few days), you must repeat the procedure, inserting a different command in the Developer mode console, i.e. :
var cookieDate = new Date ();
cookieDate.setFullYear (cookieDate.getFullYear () + 1);
document.cookie = "VISITOR_INFO1_LIVE = fPQ4jCL6EiE; expires =" + cookieDate.toGMTString () + "; path = /";
In practice, a cookie is installed on the PC that says to keep Youtube with the new graphics.
Obviously if you delete the cookies of Firefox or Chrome everything returns as before.
