That doesn't make any sense. Firefox isnt old (the last update was on march 21) and if a file is old in terms of software (not hardware) usually is easyer to read. I think that the problem in this case is that all the supported browsers are chromium-based unlike firefox.
Mate, last Firefox update was last month, give me a break. It's perfectly modern and most of us Linux users use it. Also, so does my computer studies teacher, and my science teacher from last year.
