As a long-time FF user I should be flattered, but it seems like a tough claim to back up. I don't see any design emphasis in Firefox on 'intelligent' users; 'free' is a little easier to believe, in the sense that the other major browsers are very tightly bound to certain OSes and/or their creators (IE/Edge on Win, Safari on OSX, Chrome on, well, lots of things). Chrome seems just as likely to appeal to the intelligent user (if their smarts run toward fast browsing), though given all its telemetry (e100.net etc.) it isn't perhaps the most free...
