Gmail Checker Lite (multi-account)

Download extension

Does what it says. Supports up to two accounts at the same time. No fancy features.A simple extension that checks your Gmail inbox and displays the unread count with a nice icon/badge. Also, sound notifications available. Probably one of the few that let you choose the feed you want. 'Primary' or 'All e-mail' are the ones available! Supports the new Inbox from Google and you have up to two accounts at the same time being checked password-less, which is great!
