This extension was specifically designed for HTML email UAT, but should work fine on any HTML page. It will show you a list of URLs pulled from the active tab and runs a redirect and URL syntax validation check on those selected. It also includes an option to open all URLs in a new window and audit images.
What’s New:
* Added Redirect Check to right-click link context menu
* Added tallies for total errors and warnings detected
* Added all of the 400 and 500 HTTP error codes with descriptions on tool tip
* Added check for alt and title check mismatch and added a warning for alt text without title text
* Fixed bug with checking a single link in plain text
* Fixed bug where script failed if there was no title element
* Updated redirect check API to return more accurate error codes
