I do have a suggestion for this browser. I am very new to Opera GX. So far the only thing that has been throwing me off is the middle click new tab missing. I keep trying out of habit, but it just is not apart of this program. I have been using Firefox for about 10+ years religiously. But it has slowed down and seems to be getting more unoptimized and sloppy. If there was one thing in this browser that could just throw me over the edge is the middle mouse click browser new tab. As far as I am aware Firefox is one the only main popular browser that supports it. It just makes quick functionally even more easy. If this can be added I would forever use this browser. I did attach a video link of what I mean by this.
