Firefox Will Try To Show You Saved Archive Of a Page Instead Of 404 Error (ndtv.com)

Firefox has announced a new add-on dubbed No More 404s in its Test Pilot platform which aims to change the way we see 404 links on the web. The add-on, Firefox says, replaces the Error 404 from missing webpages, and replaces them with saved archives from the Wayback Machine. From a report on Gadgets 360: Normally, when presented with a missing link, the browser shows the 404 error. However, Mozilla's No More 404s add-on will give Firefox users the choice to see old Internet snapshots saved in the Internet Archive's Wayback Machine. This is especially handy for users trying to do research or just digging up some old graves out of curiosity. For now, this add-on is only available in Firefox's experimental Test Pilot platform, with no details on availability for regular Firefox users. Interested users can install the test version here. Apart from this, the Test Pilot platform also introduced improved search results through the Awesome Bar, redesigned the Tabs bar to the side, and even tweaked the history feed.

      If people access your web services through Firefox and there is a 404 error, then I would think that your service will probably appear broken or will malfunction for that user. You may be able to intercept the error (catch the 404 return code) and direct the user to another page.

      Firefox should disable this 'feature' by default, but of course they won't.
