There is a way to change the System Fonts data?
I tried removing Flash, Java and installing a bunch of plugins, nothing works.
How the fuck do they know what fonts I have installed?
How can I spoof this shit?
Also , what are the most common user-agents , System fonts , etc?

Disable flash and js and you'll be fine, as those 2 leak such info. If you cant live without them, work from a sandboxed ebvironment such as a VM or only used cached links of websites, such as archive.is

>most common user-agents
Latest version of Chrome for Windows 7/8/10. Chrome for Android would be pretty common as well but it would be unwise to spoof your desktop/laptop as a phone since there are ways to tell (e.g. you can just check if vibration is available), not to mention websites will serve you the mobile version if available.

>System fonts
The default ones for Windows.

If you use Linux you could install Windows 10 in a VM, move the default fonts out of it and place them in a new directory in /usr/share/fonts (run fc-fache to update font cache), then use firejail to blacklist the paths of the other fonts so your browser can't see them. I believe for Windows, Sandboxie allows you to blacklist paths as well so you should blacklist the paths of the non-default fonts.

I will try this.
firejail seems pretty awesome

I tried blocking pretty much every file in the following directories:

/usr/share/fonts/
/usr/share/fontconfig/
/usr/share/ghostscript/fonts
/etc/fonts/
/etc/X11/fonts
/boot/grub/fonts /*KEK*/


Panopticlick is still able to know what fonts I have installed.
What other directories should I blacklist?
>>
>>58989139
Your system doesn't use the fonts directly, it uses the font cache, when you add new fonts the cache gets rebuilt :)

How can I fool firefox then?
>>
>>58989278
Turns out Firefox is actually working on a way to control which font the browser can access:
