You obviously never used Opera 12 :) power user in a browser has the same meaning as everywhere else - someone who is more skilled at using a tool than the average user. For example a regular user will go back to the previous page by pressing the 'back' button, or 'backspace' if they're keyboard inclined. A power user would use the "hold right click - press left click" mouse gesture (or a different variant that involves holding right click down and moving the mouse), which shaves some time off from the whole operation. Same for switching tabs (hold right click + scroll mouse wheel), opening new tabs (mouse gesture), customizing tabs (e.g. on the left side if you have the screen space) and generally knowing what options and features your browser offers. This basically means that as a power user you can do whatever a regular user can do, but more efficiently. It's not a thing to be proud of, or some sort of weird imagined superiority as you put it, it's a fact that in a browser I can do stuff much more efficiently than most of my peers. Of course, this doesn't really matter unless your job revolves around a browser, in which case you could probably shave 10 or more minutes per day (relevant when juggling with tabs a lot, for managers/P.O.s/Scrum masters and such). Of course, the term "power user" doesn't make sense when talking about barebones browsers (like the old IE), just like it doesn't make sense in Git (where everywhere needs to be a power user, you can't just casually use it like in Hg, without spending lots of time learning it).
