There are a lot of web sites out there which are for Microsoft Internet Explorer (IE) only. Most of them could fail to be rendered on OSS web browsers, such as Mozilla Firefox, due to the lack of validation by content authors, the use of IE's proprietary tags, or differences in CSS interpretation and JavaScript behavior between browsers.
TouchUpWeb intends to reduce such vendor lock-in caused by browser dependency and provides filtering utility to fix these problems. It makes modifications to the content dynamically to allow OSS browsers to render the web sites properly.
The TouchUpWeb system is made up of the server to deliver patch data and a module to modify web content dynamically. The server manages and provides patch scripts to fix varied web sites that contain dependency issues. The modification module, to be released as extension for Firefox, searches for patch script data and tries to fix content if the scripts are available.
