I just wish chrome wasnt so fucking useful by comparison. its integration into my android phone is equal to none. the firefox browser on android is ok but it does not integrate quite as well as the whole google platform. then there's the performance on linux. I hate to say it but chrome feels so much smoother and nicer to use on linux than even firefox does. I've tried making the full switch to firefox several times, last time I daily drove it for probably almost 3 months but eventually found my way back to chrome, it was just a more enjoyable experience.
then there is the fact that every website builds their code to ensure it works with chrome, that is one advantage of chrome being the vast majority of the browser user pool, web devs can focus on making sure the one thing works really well.
that all said, just like wine and linux, it is important that we have a completely separate alternative so we're not entirely reliant should the ship start to sink. I've already fully converted to linux and its been my daily driver for a few years now, not looking back. I know plenty of people are still on windows but with ever new release it feels like they're doing more and more to punch holes in the SS.Windows ship and i'll eventually be a sinking boat for enough people who see that an alternative exists. Same will need to be said for chrome vs firefox
