Classic Add-Ons Archive

Classic Add-Ons Archive is a website that archives and provides downloads for legacy add-ons and extensions for Mozilla applications like Firefox. It serves as a library of outdated and unsupported add-ons.

What is Classic Add-Ons Archive?

Classic Add-Ons Archive is a website dedicated to archiving legacy and outdated Firefox add-ons and extensions that are no longer supported or available on Mozilla's official add-on site. As Firefox updates and evolves, many previously popular add-ons cease to function properly or meet security standards.

Rather than let these add-ons disappear forever, Classic Add-Ons Archive aims to preserve them and make them available for download, even if they only work on older versions of Firefox. The site contains hundreds of old extensions ranging from themes and toolbars to productivity enhancers and fun novelty add-ons.

While the add-ons are not updated or vetted, the site itself is actively maintained. Users can browse by category or search for specific legacy add-ons they miss. Advanced users may enjoy experimenting with running obsolete extensions on newer Firefox versions. Overall, Classic Add-Ons Archive serves as a nostalgic library of the Firefox extensions of yesterday.
