I think multi container accounts are too niche to move the needle, but mobile extension and better ad block are fair points. > What features does Chrome provide in the last year (that presumably would not yet be copied by Firefox)? That's the thing though, when you are ahead you can coast on being the same. When you are behind you don't have that luxury. You have to be better in some way and not just mildly (i.e. you need some killer app). If marginally better was enough we would all be using plan9. Maybe the ad blocking story can become that for firefox, but i think chrome would have to get a lot more heavy handed before that can really become a marketing win for firefox.
