Total Validator Firefox Plugin

I would highly recommend this Firefox plugin to any web developer.

I have never seen such a comprehensive list of features in a validation plug-in before!

• HTML validator
• An accessibility validator
• A spelling validator
• A broken links validator
• The ability to take screenshots with different browsers to see what your web pages really look like (27 different browsers supported!).

It also has the ability to upload local pages to the total validator service (great if the web site isn’t actually live yet).

Note: They also offer standalone versions for windows and OSX and a “pro” version that can spider through and validate an entire site. The Firefox extension works well on Linux!
