Trivalent
What Trivalent is
Trivalent is a free, open-source browser for desktop Linux that uses Chromium and focuses on security. The project is intended for use in secureblue and includes desktop-oriented patches from Vanadium. Its stated work covers hardening against known and unknown vulnerabilities. Secondary functions, including the password manager and search suggestions, are opt-in. Trivalent also disables opt-in metrics and data collection when doing so does not create security implications. Chromium’s internal subresource filter enables content filtering by default. Security and privacy preferences are available at chrome://settings/security, including a Network Service Sandbox toggle that is disabled by default. Optional flags can display punycode domains or clear cross-origin referrers, although these may cause breakage or usability issues. The default pop-up blocker is very strict and can be disabled. Official support comes through secureblue; repository installation is unsupported. Community help is available through GitHub issues and Discord. Vulnerabilities should be reported privately through a form.
