Chrome: You won't find a shortage of tab management tools out there for Chrome. Veritabs is an extension that adds a vertical sidebar to your browser to help you easily find the tab you're looking for.
Veritabs is barebones, but does exactly what it says. Hit the Veritabs icon, mouse over the top left corner of your browser window, and you get an easy-to-read sidebar listing all your open tabs. That's pretty much it. Veritabs isn't packed with a lot of features, but it achieves its goal well.
