Update: URL Fixer was acquired and is now hosted at http://urlfixer.org/
I’ve updated URL Fixer to version 1.2.12. In addition to including a Catalan translation, there are two main changes to the correction algorithm:
1. “;//” will now be corrected to “://” (http;// => http://).
2. All commas and other semicolons will be changed to dots (www,google;co,uk => www.google.co.uk).
