Why did Firefox main versions start to grow so fast after 2011 april (FF4)?
It is version 13 now and rapidly growing.
I read the Wikipedia article about it, which says that they wanted that users always have an up-to-date version of Firefox. But why are minor versions not appropriate? Like 4.1, 4.14, etc.
It was to keep up with chromes naming scheme for their updates, essentially uses naturally thinking bigger changes were made with a major revision change vs. a minor one.
