Fix the Web's goal is to promote a World Wide Web built on solid, standards-compliant web development practices so it is usable for everyone.
Additionally, a browser masking feature is available which masks the Navigator object as the selected browser. This does not modify the user-agent string sent in HTTP requests, so this won't necessarily fix browser-sniffing problems.
IMPORTANT NOTICE: no badge will be displayed until we update certain code on Fix the Web's server.
Because most of our time is going towards the development of the extension, we are not creating many patches right now. But please keep reporting broken web pages so that we can write patches for them in the future and/or contact the site owners.
The project is open source, so your contributions would be appreciated. Learn more about the project here: http://my.opera.com/fix-the-web
