Welcome to the Fierr home page! Arguably one of my more popular programs, Fierr has a long history of making network errors look better.
The most noticable change Fierr introduces is the actual error screen. A new layout provides large, clear information about the type problem your browser had loading a page, complete with background and icons to match your browser.
After ten seconds, the error page will try to reload unless you click the Stop Reload Button beforehand. If your browser is in offline mode, a Go Online Button will be displayed so you can quickly get to the page you need. If the page doesn't load, you can use the Search Button to try to find the site you're visiting.
Want to change the style of the error page? You may now create a custom version
of the extension with your own personalized Background Image

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
extension that still supports older versions of Firefox
