Alrighty! I've been trying to re-find that ticket for quite a few weeks.
Used it many months ago and promptly lost it. Thanks. I will pass on the
ticket number to the Tor Uplift guys
> it's possible to detect some distros such way
Comment 18 was 5 years ago. So far, and my resources are limited (and as
an upstream problem means more than Tor Browser, which already changes
their math FP), I have found nothing so far that leaks anything more than
major platform (win/linux/mac) and in some instances 32/64 bit builds or
OS architecture (some by default: eg a 64 bit build must be on a 64bit
OS).
I wanted to get a ticket at bugzilla opened. I have no idea how much work
or complexity and potential issues lie with using the same libraries over
all platforms (which is what Chrome seems to be doing: they have the same
FP regardless of anything I test on).
