I2P Browser Configurations and their Attackability

This information was never very complete, and it is currently out-of-date. I am working on updating it to reflect the current set of recommendations.

Testing the attackability and fingerprintability of various browsers in an i2p context, and where possible, reducing it via whatever available configuration.

Semi-Official Firefox Browser Profile

I2P in Private Browsing Mode Firefox Extension

These 2 screenshots are from the same Firefox at the same time. As you can see, the fingerprints differ and obuscation measures have been taken.
