Genuinely wondering, why Chrome? IE11 has a really awesome touch UX, in the metro version, IMO. Did you try it and dismiss it, or not even consider it given IE's track record?
Ecosystem traps people if I want to be cynical. I do everything on Chrome from personal to work, all my favorites/bookmarks are synced through all my hardware.
Even if there was a sync option for IE to Chrome accounts this is just extra effort. You put too many steps in front of me I'm just not gonna do it (yes, I'm lazy, but UX should consider the lazy).
Firefox supports 1Password, MightyText, Adblock, Disconnect, Privacy Badger, Zotero, and a variety of other plugins including multiple HTTP clients and a top notch dev console.
So, I deleted the comment where I applaud IE yet describe the extensions you just rewrote in almost parody (edit: misread Firefox on my mobile device as IE. Good point! I love Firefox too for these reasons!). But, my point is that the metro IE doesn't have extensions. Chrome does (the metro edition) because last time I checked it's just a frozen implementation of the desktop browser but full screen. Lack of extensions is the weak point for me for any browser. And, the metro IE and better scaling overall are the only compelling benefits I see to IE. So, I usually opt for Chrome (edit: or even firefox! :) )
