Mercury Browser

Privacy-focused Firefox fork with compiler optimizations and patches from Librewolf and Waterfox

Desktopfreeglobal

Mercury is a privacy-focused Firefox fork combining compiler-level performance optimizations with privacy patches drawn from Librewolf, Waterfox, Ghostery, and BetterFox. It's built as the Firefox equivalent of the same maintainer's Chromium-based Thorium browser, aimed at users who want a faster, more private Firefox without switching to a Chromium-based alternative.
