Extremely helpful and versatile Rated 5 out of 5 stars

I use Tile Tabs all the time, but typically only activate it to view two tabs side-by-side (left/right). I most commonly accomplish this with F12 because I don't like using the drop-down menus. If I have numerous tabs open and I do not want to change their order, I use the "shift-drag" mouse function. To tile tabs that are not next to each other, simply do the following:
1. view one of the tabs you want tiled
2. hold "shift"
3. drag the tab you want tiled over the window of the tab you're currently viewing - an icon (labeled "Above," "Right," "Left," or "Below") will appear to the left of the cursor depending on where the cursor is on the window

Thanks for writing this extension!

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!
