Waterfox is a free and open-source web browser and fork of Firefox. It claims to be ethical and user-centric, emphasizing performance and privacy. There are official Waterfox releases for Windows, macOS, Linux and Android. It was created in 2012 to provide official 64-bit support when Firefox was only available for 32-bit systems.
Waterfox shares core features and technologies like the Gecko browser engine and support for Firefox Add-ons with Firefox. It is also compatible with Google Chrome and Opera extensions. It disables telemetry by default, which is present in Firefox builds. However, it collects technical information about the user's device to update properly.
Waterfox Classic was a version of the browser based on an older version of the Gecko engine that supported legacy XUL and XPCOM add-on capabilities that Firefox removed in version 57. It was partially maintained with fixes and patches from Waterfox and Firefox ESR releases. However, its development had been separated due to several changes from Waterfox that were otherwise inapplicable, and with its final published release in November 2022 it is effectively discontinued as of 2026.
