What is Konform Browser?

Konform Browser is a web browser for Linux with the goal of promoting user freedom and access to the rights of security, privacy and anonymity. It is intended as a general-purpose browser fit both for daily online browsing as well as targeted deployments in secure or untrusted environments. On a technical level it is fundamentally a patched build and custom configuration of Mozilla FireFox ESR originally starting as a fork of LibreWolf. It also inherits heavily from Tor Project's BaseBrowser. The project has no affiliation with either Mozilla, the LibreWolf Maintainers or Tor Project but pays gratitude to its benefactors.

Things like original FireFox AI features, telemetry, WebGL and some other Freedom/Privacy/Security problematical features are disabled by default. However, some other settings like Dark theme for web content seems to be enabled (unlike for instance LibreWolf that forces light theme for fingerprinting/privacy concerns ).

Konform supports uBlock Origin.

🐧Supported Linux distros via official Konform repositories:

🌐 All languages supported in original FireFox browser should indeed be supported in Konform.
