Modern browsers ship with significant bloatware that can be disabled via settings or policy files. Creating a JSON policy file at the appropriate system path allows users to de-slop browsers by force.

For Firefox, policies can disable telemetry, pocket, Firefox accounts, and studies while enabling tracking protection and setting DuckDuckGo as the default search engine. Additional configurations include disabling Captive Portal, feedback commands, and enforcing HTTPS-only mode.

Chrome policies similarly block third-party cookies, disable autofill, sync, metrics, and password managers. Custom certificate authorities require workarounds since direct policy support was removed.

Both browsers support extension management through policies, allowing forced installation of ad blockers like uBlock Origin with predefined filter lists. Users should consult documentation for each setting to ensure configurations meet their needs.
