Simple Plugin/Add-on for IE & Firefox & Chrome

The goal of this project is simple. Instead of having a user browsing to a website, we would like to have a single button plugin which splits the browser into two parts loading two different websites. The websites may have mutual interaction. So clicking a link in the left frame should be able to change the location of the second frame and also the other way around. Their should be a splitter, such that you can change the size of the left and right frame. The URL displayed should resemble the website of the second frame. Difficulty is to design three plugins with the same behavior for the main browsers (with the main versions) of IE, Firefox and Chrome. The plugins should be installed easily and the filesize as well as load should be minimal. ## Deliverables * Button in control bar (with small logo) * Resizable frames * Interaction between frames * The frames may be closed (together) * Fast & lightweight, correct memory usage * Documentation * A plugin suitable for Chrome (version larger or equal to 8) Under popular versions of Windows, Linux & Mac <!-- --> * A plugin suitable for Firefox (version larger or equal to 3.5) Under popular versions of Windows, Linux & Mac * A plugin suitable for IE (version larger or equal to 6) * One click download, accept and install wizard for plugin/add-on * No dependency on licensed software (if really required, discuss first)
