Uhh, maybe you should try that in Chrome. The very first item on the drop down menu that comes up is the back button and no you don't need to release right click to click on it. Also, it's even faster than Opera, you can just right click and then release it over back and not have to left click at all.

It's not using 'back'. It's a 'rocker' gesture to navigate between tabs. Right click anywhere, then left click while holding it, move to the left tab. And vice versa.

I may be confused what you're referring to, but switching between tabs is right click + scroll wheel.
