Mozilla has unveiled a new Firefox experimental feature which will get rid of the 404 page.
According to Mozilla’s Test Pilot platform, the No More 404s feature will replace missing web pages with archived entries from the site being visited.
The 404 add-on is powered by the Internet Archive’s Wayback Machine.
Mozilla’s add-on won’t work if there’s no Wayback Machine entry for the page, stated The Verge, or if the site automatically redirects a browser to another page.
The 404 feature is currently only available as an experimental add-on.
