 I recently changed the default system locale on my GNU Linux system, and I
 noticed that afterwards the default font used on web pages in Tor Browser
 had changed (I didn't change the version/language of Tor Browser).

 I suppose that this means that an attacker can guess a user's locale based
 on the font used to display a page.
