Split Browser

Split Browser is an add-on for Firefox that allows you to divide the Firefox interface into several panels and open a different website in each panel.

This add-on can be really useful if you need to check data in different websites at once or if you need to copy some data from one website and check it in other one. It is also very helpful if you want to access your social communities and stay up to date at a glance.

Split Browser offers different view modes and allows you to organize panels horizontally, vertically or in a mosaic. You can set the size of each panel just dragging the borders.

Each panel is independent from each other and if you want to view any panel in fullscreen, you can convert each panel into a tab and browse Firefox as usual.
