Security/Fingerprinting
Cross-Origin Fingerprinting Unlinkability
The anti-fingerprinting project is part of the Tor Uplift project.
Its goal is to build up the same level of fingerprinting resistance as the Tor Browser in Firefox.
Refer to the design and implementation document of the Tor Browser:
https://www.torproject.org/projects/torbrowser/design/#fingerprinting-linkability
Project Schedule
- Complete the implementation of MVP in Firefox 57 (2018-09-20)
- This is being tracked by three milestones M1, M2, and M3
- Feature stabilization and refinement in Firefox 58 (2017-11-13)
- Perform integration test to identify regressions and Web compatibility issues
- Perform tests to verify the effectiveness of fingerprinting protection
- Fix regressions and any other issues
- Figure out the product strategy of Firefox to roll out this functionality
- Ship the feature in Firefox 59 (2018-01-15)
- Tor Browser will be using Firefox ESR 59
Bug Tracking
All fingerprinting bugs are being tracked under the meta bug:
bug 1329996 - [META] Support anti-fingerprinting protection
Priority Definition
- P1: MVP (Minimum Viable Product)
- P2: Nice to Have
