Why people choose FoxFilter
A flexible content filter that adapts to how you want to use it — on one device or across every browser you own.
Block sites and keywords
Block whole websites, or let FoxFilter scan for keywords across the web. A starter keyword list comes built in — add your own any time.
Whitelist & Blacklist Controls
Allow the sites you trust (allowlist) and block the ones you don't (blocklist). Exceptions work at the site and keyword level.
Password protected
Lock your configuration behind a password so the settings can't be changed — available with any subscription. Password recovery is available if you forget it.
Sensitivity you control
Turn filtering up to scan page content, or ease off if too many normal sites get blocked. Adjust any time.
Private by design
Filtering happens on your device. Your browsing history, page content, and activity are never sent anywhere.
Nothing extra to install
It's a browser extension — no separate app, no system services, no reboot.
Works across the places filtering matters.
Personal devices, family computers, shared workstations, and managed endpoints all benefit from the same setup.
Home & family
Install on each browser in use, set what's blocked, add a password (with any subscription), and turn on extra protection so the configuration stays put.
Schools & libraries
Deploy across shared devices using browser-level policies. No content-filtering server to run.
Organizations
Meet acceptable-use expectations on managed laptops without a full enterprise filtering stack.
