I use a ton of tabs in my browser, in Firefox the tabs go off to the side and allow me to scroll through them (while still allowing me to read the title) whereas Chrome squishes the tabs into tiny micro-sized pills that are completely unreadable.
Additionally I use App Tabs in both browsers - but only in Firefox does it highlight when I've received an update (such as a message in Hip Chat or an email in Gmail).
The lack of integrated extensions in Chrome makes for a weaker overall experience. I use PasswordMaker to manage my passwords - works great in Firefox, can enter passwords into any field, but in Chrome it frequently doesn't detect a password field - and since it doesn't have context menu access I can't fill in my password. I end up having to open up Firefox just to get to my password.
So yeah, I still use Firefox for daily browsing, and Chrome for dev.
