Firefox is among the most secure mainstream browsers. Still, there are some loose ends. I recently stumbled upon this post that features Firefox privacy recommendations and tweaks to strengthen Mozilla browser security.

- Disable telemetry to prevent Firefox from sending usage data to Mozilla
- Change your default search engine to a more privacy-friendly one, such as DuckDuckGo or Startpage
- Enable tracking protection to block third-party trackers by default
- Turn on the Do Not Track Protection to request websites not to track your browsing behavior
- Disable the WebRTC to prevent your IP address from being leaked
- Remove DRM to avoid installing proprietary software that may compromise your privacy
- Install some recommended security add-ons, such as:
- uBlock Origin to block ads and malware domains
- Privacy Badger to block invisible trackers and learn from your browsing behavior
- HTTPS Everywhere to force websites to use secure HTTPS connections
- No Script to block scripts from untrusted domains
- uMatrix to control the requests that your browser makes
it's also quite wrong:
- DNT requests can be ignored and are an additional data point to identify you (although the recent LinkedIn ruling could be a light in a tunnel)
- Privacy Badger doesn't do anything uBlock Origin doesn't
- HTTPS Everywhere isn't needed since the option is now built into Firefox itself
- you can block scripts with uBO, no need for NoScript
- uMatrix has been deprecated
