Mouse Gestures, Screenshots and Pop-up videos, first warning

I need a browser’s built-in mouse gestures option. I know there are addons like crxmousegestures but they do not work properly, i also know there are addons for screenshots, they do not work properly either, all the same with the Pop-up videos feature. I think Opera’s screenshots, mouse gestures and Pop-up videos are the best by far, and thats the reason it is mine main browser for now.

Sincerly yours
