This is the same problem that modern Windows has: these systems are designed by 20-something year old designers who wear specs with thick coloured frames and who only use Mac and Safari. They don't give a shit because they don't have to use these systems ever; for them these systems are something they screenshot and put in their portfolios.

The graphic design of Firefox is not made by developers, it's made by designers who don't use Firefox.
