@weirdnemo Sorry for my delay, this extension is simply called "swipe-back" and is available on the Chrome Web Store since Opera is a Chromium-based browser. Here is the link below! It works greatly for me on all my Windows computers, enabling both previous and next swipe functionality like Chrome. Hope this helps you!

Opera supports Chromium extensions, so you should be able to install a gesture-based one as I have. I sadly don't remember which one I'm using, but the simple two-finger back and forth gesture option does exist on both my Mac and Windows versions of Opera after downloading an extension for it.
