This extension gives you a stylish error page with three buttons: Back, Reload, and Search. The background image of the error page is a high quality 500x500 logo matching the product. If the error can be fixed by reloading, the page will automatically reload in ten seconds, with a button to stop the reload. The Working Offline error page includes a Go Online button for quick access to online browsing.

Since Fierr's final release for Firefox in April of 2015, Mozilla has abandoned its own technologies in favor of poor parody of Google's protocols (WebExtensions), leaving many developers, including this one, disillusioned with the direction the Mozilla is taking. In contrast, Pale Moon has stepped into place as an XUL-centric browser, keeping backward compatibility better than Mozilla's own flagship project. So, for now, Fierr may be considered a Pale Moon and SeaMonkey extension that still supports older versions of Firefox.
