Error Page Enhanced replaces the default browser error page when you cannot connect to a URL, with information about the failure and links to various services to diagnose a problem, or to research, register and develop the domain. V2 also includes: one-click copy URL, HTTP/HTTPS switch, auto-retry with exponential backoff, and domain typo suggestions for DNS errors. Kiosk mode and customisable timer, and per-button toggles. Great for domainers who want quick access to check out available domains, for web developers to diagnose problems and for anyone who wants more information about why that website isn't working right now. Links to: Whois Ping Traceroute Domain Root Archive.today Google Search Web Proxy DNS Lookup Register Domain (GoDaddy) Wayback Machine Down for Everyone It logs or uses zero data and never communicates with anyone else, it's just adding a screen with links to the services listed when you encounter a failed page request. Please rate/review the extension with your feedback and I'll update with additional features requested. NOTE: The extension has to change the page url. The browser's default error page content cannot be modified by an extension.
