> the only area where Firefox previously had a massive advantage over Chrome. It didn't though, because the API was different a lot of extensions that appeal to a broader user base were not made available on firefox (anymore). Yes, the previous framework did allow other use cases more suitable for power users but those are a fraction of the total user base. And in general it hugely simplified extension development. Instead of having to maintain various code paths for different browsers and accounting for slightly incompatible APIs this was no longer needed.
