The fastest web browser has its weakness. When you middle-click on a URL link to open its new tab, the mother site goes backward. That means you mess up what you are browsing. I was surprised to see that the Opera team still has not fixed this tedious error over their 10th version. Here comes how to fix it. Type below in a terminal window.
sudo nano /usr/share/opera/ui/standard_mouse.iniDelete the 2 options:
Button6 = Back
Button7 = Forward
