Re: [tor-talk] TBB does not employ fontconfig settings



Hello,

To answer your question you might find the Tor Browser design document
[0] a useful read. Font support leads to browser/system
fingerprinting. Plugins and scripts can extract font support lists,
html5 canvas elements can be used together with font
support/rendering, and the way fonts are rendered can lead to OS and
video card driver fingerprints.

tl;dr -- Font-support based fingerprinting remains an open-issue in
the current version of TBB.
