Rated 5 out of 5 stars

I feel like this addon should be part of Firefox's default functionality. Tile Tabs allows the user to have the convenience of tabs with the reference functionality of windows, all while providing a greater viewing area and less hassle than windows. Awesome for referencing between webpages for comparison and formulas. Easy to use and non-intrusive, just drag your tabs next to each other and hit F12!

This review is for a previous version of the add-on (6.1).
