Waterfox is an open-source web browser for x64, ARM64, and PPC64LE systems. It is intended to be ethical[citation needed] and (in Waterfox Classic) maintain support for legacy extensions dropped by Firefox, from which it is forked. There are official releases for Windows (including a portable version), Mac OS, Linux and Android in two versions: Classic and Current.

Waterfox is based on Firefox (and uses Firefox's engine) and is compiled using various compilers and using Intel's Math Kernel Library, Streaming SIMD Extensions 3 and Advanced Vector Extensions.[not verified in body] Linux builds are built with Clang on all architectures other than PPC64LE. Waterfox Classic is continuing to support the long-standing XUL and XPCOM add-on capability that Firefox removed in version 57.[2][3][4][5]


The features of Waterfox currently are:[6][7][8]

  • Compiled with Clang+LLVM on Linux
  • Encrypted Media Extensions (EME) is disabled by default
  • Web Runtime is disabled (deprecated as of 2015)
  • Pocket is removed
  • Telemetry is removed
  • Data collection is removed
  • Startup profiling is removed
  • All 64-bit NPAPI plugins are allowed
  • Unsigned extensions and legacy add-ons are allowed from the following sources: Archived Add-ons for Firefox, LegacyCollector, Thunderbird Firefox Add-on Archive, Classic Add-on Archive Extension, Add-ons for Firefox, Chrome Webstore.[9]
  • Sponsored tiles on the new tab page are removed[10]
  • A new "Duplicate Tab" command is added
  • A locale selector is added to about:preferences > General (further improved by PandaCodex)
  • Cookie Prompt has been re-implemented. Firefox later implemented a more advanced cookie control feature as part of its tracking protection initiative
  • Passwords and logins manager
  • Synchronize bookmarks, history, tabs, passwords, add-ons, and preferences across devices
  • Bing is used as the default search engine

Waterfox was first released by Alex Kontos[11] on March 27, 2011 for 64-bit Windows. The Mac build was introduced on May 14, 2015 with the release of version 38.0,[12] the Linux build was introduced on December 20, 2016 with the release of version 50.0,[13] and the Android build was first introduced in version 55.2.2.[14] Version 29.0, released on July 22, 2015, had a build for iOS.

From May 12, 2015 to November 12, 2015, Waterfox had its own exclusive charity search-engine called "Storm".[15] After using Ecosia as the default search-engine for a brief time, it now defaults to using Bing.

On May 7, 2019, with version 68.0a1, the first alpha version of the next generation of Waterfox was released based on Mozilla's Quantum project (used in Firefox versions 57 and later), which would be named Waterfox Current.[16]

In October 2019, the naming scheme of releases changed to follow the syntax YYYY.MM.X for future releases, where X indicates incremental hotfixes. There was also a division into two branches, classic and current.

In December 2019, System1, an advertising company which portrays itself as privacy-focused,[17] acquired Waterfox.[18][19]

In November 2020, Waterfox G3 was released. It is based on Firefox 78 ESR.[20]


In February 2020, Alex Kontos faced criticism over selling Waterfox to System1, an advertising company.[21][22]
