Firefox Profilemaker is a web-based tool that helps you generate customized Firefox profiles with your preferred default settings. Instead of manually tweaking Firefox’s configuration files, you can use this tool to select which features you want enabled or disabled, and then download a ready-made profile template as a ZIP file.

Features:​

  • Customization of defaults: Choose which browser features, privacy options, and security settings you want active.
  • Disable unwanted functions: For example, you can turn off Pocket integration, telemetry, or other background services that send data to Mozilla or Google.
  • Privacy-focused options: Includes settings to reduce tracking, disable DOM storage, disk cache, or browser pings.
  • Enterprise policies: Useful for organizations that want consistent Firefox configurations across multiple machines.
  • Explanations provided: Each setting comes with a short description, and links to resources for deeper understanding.

Useful resource, but it’s best to frame Firefox Profilemaker as a “configuration generator” (prefs/policies + optional add-ons), not as a security hardening tool you should apply blindly.

What it is (and what it isn’t)
It generates downloadable templates like profile.zip, prefs.js, and an enterprise_policy.zip, based on a wizard of toggles. ([ffprofile.com](https://ffprofile.com/?utm_source=openai))

It’s also explicitly not affiliated with or endorsed by Mozilla, and the code is published so you can review/self-host if you don’t want to trust the hosted instance. ([github.com](https://github.com/allo-/firefox-profilemaker))

Main security/privacy “gotchas” to watch for
Some privacy-oriented toggles can reduce real-world security or make incident response harder. In particular:

  • Disabling Safe Browsing / malware checks: reduces protection against phishing/malicious downloads (even if the privacy rationale is understandable). ([ffprofile.com](https://ffprofile.com/))
  • Disabling update mechanisms: anything that delays or discourages timely browser updates is usually a net negative for security. ([ffprofile.com](https://ffprofile.com/))
  • Disabling Mozilla’s extension blocklist: can keep known-bad extensions running, which is a tangible security risk. ([ffprofile.com](https://ffprofile.com/))
  • “Breaks things” privacy switches (e.g., IndexedDB/WebRTC/WebGL): can improve privacy in some threat models, but may cause site/app breakage and lead users to add compensating extensions or unsafe workarounds later. ([ffprofile.com](https://ffprofile.com/))

Safer way to use it
  • Apply to a brand-new test profile first (don’t overwrite your daily-driver profile until you’re confident). Mozilla’s Profile Manager guidance is a good reference for managing multiple profiles safely. ([support.mozilla.org](https://support.mozilla.org/en-US/kb/profile-manager-create-and-remove-firefox-profiles?utm_source=openai))
  • Prefer “prefs.js only” first so you can review exactly what’s being set before importing a full template. ([ffprofile.com](https://ffprofile.com/))
  • Review what you’re enforcing via enterprise_policy.zip: policies are powerful because they can re-apply settings at each start (great for org consistency; risky if you forget what you enforced).
  • Keep Firefox’s core protections enabled unless you have a clear reason (Enhanced Tracking Protection / cookie isolation protections are already strong defaults in modern Firefox). ([firefox.com](https://www.firefox.com/en-US/user-privacy/?utm_source=openai))

Bottom line
Firefox Profilemaker can save time and make configuration more understandable, but it can also accidentally weaken protections if you select “privacy” options that disable security controls. The safest approach is: generate minimal output, review it, test in a separate profile, and avoid disabling updates/Safe Browsing/blocklists unless you fully accept the trade-offs.
