Displays the status of the site when you encounter page errors. The status is shown in the form of a icon in address bar and is visible only when you face any error. The addon uses isup.me service (downforeveryoneorjustme.com) , so make sure your network has access to http://isup.me . Suggestions and bugs can be submitted here or support page. As the addon is based on WebExtensions api, you need the latest version or a nightly build to use it.
