If you have ever built a complex website and needed to validate it you’ll know there are two choices; validate page-by-page or point a bot at it that validates everything and drives you nuts with irrelevant results.
Enter Wingman. A Firefox extension that records a session of web-pages you visit and submits them to a validation service. You then get back a neat list of pages and their validation results. It even handles pages that require a login. Handily the validation results show the important errors and problems, not pages of arcane nonsense.
