Safari Validator is a Safari extension which allows you to validate your website for (x)html compliance. The actual validation is done by Tidy and the W3C validator.
What's new in this version:
Implemented HTML5 validation (by using external service html5.validator.nu) Fix W3C report showing blank screen (was a Safari security measure) Added a toolbar button (with ugly logo) to quickly toggle validator bar Remove border at bottom of websites caused by the validator embed (thanks Veerle!) No embed-injection in iframes anymore (for rich text CMS editors)
