I've included a screenshot of the site settings page for so you could actually see what I'm talking about. Of course this is what I call 'food for thought'. I'm sure that if I understood more about adding a script or coding it would probably be highly possible to add that so videos wouldn't play automatically. I'm still hoping that at least some kind of video auto play feature eventually gets implemented into this browser.

At least for me anyway, that one option surely wouldn't make me want to quit using vivaldi and actually switch to brave as my default browser. At lease the times when I have used that browser for experimentation purposes as well as reference purposes, that particular setting seems to actually function pretty well.

With that browser at least every site that you visit has a link to 'site settings' where you can actually tailor quite a few individual settings to suite your individual tastes, and of course on sites that contain videos there's an option for the auto playing of videos where you can set it to 'block' that from happening. Just for reference sake & of course NOT trying to be rude to any of the developer's of this browser, but a feature such as the developer's of the brave browser has implemented & seems to function pretty well is included up in the address bar on the left hand side. While I still enjoy using this browser I would surely enjoy using it a lot more if at least SOME kind of mechanism could get implemented so as to at least prevent SOME of the html5 videos from auto playing.
