Waterfox
Waterfox is an open-source web browser for x64, ARM64, and PPC64LE systems. It is intended to be ethical and (in Waterfox Classic) maintain support for legacy extensions dropped by Firefox, from which it is forked.

Linux builds are built with Clang on all architectures other than PPC64LE. It is compatible with extensions written for Mozilla Firefox, Google Chrome and Opera.

Waterfox Classic (Year.Month)
Waterfox Classic is continuing to support the long-standing XUL and XPCOM add-on capability that Firefox removed in version 57.[6][7][8][9] The "Classic" version is actively supported, based both visually and internally on an older version of Gecko, and supports add-ons from XPCOM and XUL.[10] Since 2017 its version remained on Waterfox version 56, for now they use the (Year.Month) format for their versioning scheme.

History

Waterfox was first released by Alex Kontos[14] on March 27, 2011 for 64-bit Windows. The Mac build was introduced on May 14, 2015 with the release of version 38.0,[15] the Linux build was introduced on December 20, 2016 with the release of version 50.0,[16] and the Android build was first introduced in version 55.2.2.[17] 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".[18] 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.[19]
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,[20] acquired Waterfox.[21][22]
In November 2020, Waterfox G3 was released. It is based on Firefox 78 ESR.[23]
In October 2021, Waterfox G4 was released.[24]
Reception
In February 2020, Alex Kontos faced criticism over selling Waterfox to System1, an advertising company.[25][26]
In 2018, How-To Geek advised users to not use Firefox forks such as Waterfox because security updates take longer to be incorporated into the forks compared to Firefox.[27]
