  Find broken links while browsing your, your client's, or your mistress's website! With its simple yet effective interface, the Broken Link Scanner works wonders in tandem with your other in-browser SEO / web dev tools. Features include:
  
  * Passively scans the webpage in the active tab of your browser as it loads
  * Optionally highlights broken links on screen conspicuously
  * Records the broke target URL, the link's anchor text, the target's status code, and the number of scanned pages found containing the exact link
  * Generates a button for a quick Google index search query with the anchor text and domain of the broken target URL. A quick "recommendation" for URL correction!
  * Offers convenient data export options
  * Comes with an Import URLs option for checking a fresh list of URLs on the fly
  * Notes the user-agent setting for each link scan - great for diagnosing device disparity issues
  * Itemize all scanned URLs and their status code if you're a nerd. Turn it on, set the DevTools Console to Verbose and see a lot more data that no one else cares about
  * Latest feature: Enter Slowmo Mode for especially recalcitrant sites that rely on rate limit blocking, throttling, or some ungodly hybrid thereof. Be warned, however: It's reaaaaaaaaal slow
  
  NOTE: Many "triple AAA"/"unicorn"/"ultra-enterprise" sites are auto-excluded, such as paypal.com and google.com.
