The idea of creating a browser-into-the-browser for Farfalla seems to be the best solution for accessibility: it will allow the rendering of webpages inside a sort of protected environment, where the pages themselves could be dinamically modified to meet the most basical accessibility requirements.

Last week I started writing some code for the new Farfalla release. As I decided to develop it like a browser-in-the-browser program, I started building a web page wrapper.In its present state, the program can only browse web pages, using a simple HTML form to enter website addresses instead of using the browser’s main navigation bar. This is the first implementation of the abstraction layer discussed before: it can change the way URLs are inserted, independently from the browser being used.From a technical point of view, this is possible thanks to the strong use of javascript for filtering mouse and keyboard events: every time a key is pressed it sends a code number to the web browser. Intercepting this code associates almost any action to the code number through javascript. This has a complication: key codes are not standardized among browsers, so the very difficult task will be to make every browser behave alike - this problem is well known as Cross Browser Compatibility.
