Farbling Tests

Crossed out items are planned, but are not currently implemented.

Test instructions

Confirm that:

• with shields up, FP values are the same for each individual item (ex. WebGL Drawing) on a given page, but the values are different between the two pages above.
• with shields up, if you close and relaunch the browser, and visit the pages again the values are different (they are not retained between sessions).
• with shields down, FP values are the same for each individual item on a given page and are the same for both pages
• with shields down, if you close and relaunch the browser, and visit the pages again, the values are the same (they are retained between sessions)

Fingerprint Values

The version column describes which version of Brave the farbling protection was introduced in.

The mode column captures whether the protection is applied when standard protections are enabled, strict protections are enabled, or both.

Fingerprint Stress Test

This test is designed to see if previous race conditions in determining if correct farbling seed is used under a variety of conditions.
