Hello,

If you are using Brave, Edge, or Opera you could see a little difference:

Part 1: Copy and paste the image

In Brave Browser or Microsoft Edge, you need to save an image copied locally however in the Opera browser you could upload directly the image from copy-paste without having to save it locally on your browser.

Part 2: Lucid Mode

It is only an Opera option because there is no extension that provides Luicid mode for videos for the other two browsers.

Part 3: Pop-out video and Autoplay:

On Youtube settings you cannot find Autoplay false you have to install remotely for Edge and Opera AutoPlay stopper.

Sometimes you need to restart the computer and you may have 2 or 3 videos that run directly after restarting the browser that seems not a good option at all which means the installation is something required to just run the video once you are ready to complete it.

Part 4: Synchronisation:

It is by default disabled in Brave Browser so you need to enable it.

Part 5: Sounds

For Opera going to settings then sounds to mute the website but for Brave, you could mute the site and for Edge, such a feature is not available so you need to turn off the music on your profile like Youtube.
