 When the uBlock Origin icon is clicked in Tor Browser and the toggles at
 the bottom of uBlock are also clicked, the icons show a red box with the
 numbers 2715 instead of a black X. This is because this very generic and
 very old unicode
 https://www.fileformat.info/info/unicode/char/2715/browsertest.htm is
 either not supported by the current fonts in TBB on Gnu+Linux or, if it is
 supported, the font fallback mechanism isn't working.
