Chrome-Stats extension

A simple tool to find broken (404 code) and redirected (301, 307, 308 codes) links in the current page. This tool examines all links in the current page (top frame and all sub-frames) and returns the status code and its meaning for each link. You can optionally ask the extension to check links inside about:blank frame elements are well. All broken links are placed in a separated category for easier detection. Beside each link, there is an inspect button which focuses the link to the center of the page to help to find the links faster.

Note that you can open the validation UI in a new popup window or as an embedded frame inside the page.

Note that this extension also notifies you about the links that are skipped like none HTTP links or mailto links

  3. Text-Link Extraction: extracts links embedded in the content that are not actual links. This feature works on the top content and all subrequests.
