Update (March 2, 2022): As a group of developers who met through the Opera Browser community, we originally started this project with plans to patch malformed web pages that were improperly rendered when using Opera Presto. Before this project was completed, Opera migrated its rendering engine to Chromium, eliminating most of these rendering issues.
Fix the Web is an extension-in-progress for Opera Web Browser. Many web pages use malformed HTML, poorly-written Javascript, or bad web development practices such as browser-sniffing. Consequently, these pages could produce visual flaws, functional glitches, or even worse, be completely nonfunctional in Opera, a standards-conforming web browser.
The goal of Fix the Web is to provide a solution to these problems by allowing users to report site problems they encounter, reply to others' bug reports, and, most importantly, apply patches to broken web pages.
Before you apply a patch to a web page, determine how it needs to be fixed. If it only needs a CSS patch, then add the patch to the CSS patches Wedata database. However, if the web needs a Javascript patch, then add the patch in the patches.js file in the includes/ folder in this repository. Read more about site patching here.
This project is open source, so your contributions will help it grow. Fork the project and contribute!
