Firefox is implementing a Tor-based security upgrade
Mozilla is making Firefox a more private experience by taking cues from Tor, the go-to browser for those who dare to visit the dark web.
The Mozilla Foundation will remove a "feature" called canvas fingerprinting from Firefox, which allows user-tracking across multiple sites without cookies, in its next build. It will do this by imitating Tor browser, which was built on modified Firefox code and already blocks tracking.
Canvas fingerprinting, which happens in every major browser, lets websites extrapolate your information by tracking you across multiple sites with a mixture of unique identifiers. This method doesn't require you to carry any tokens or accept a cookie.
This is great for advertisers and websites, but not for anyone opposed to having their data commoditized without being asked first.
Mozilla doesn't appear to care if advertisers make money, or if Facebook's AI can figure out which ads you're most likely to respond to, or if it's making enemies in the FCC.
The developers and artists at the Mozilla working both directly on Firefox, and indirectly on other projects, all appear to share a common goal to get people aware of what's happening with their own data and empower them to gain control over how it's being used.
