These tests are sketchy - I have been awarded 17.85 bits on this browser however 13.94 bits come from one line item: > System Fonts Arial, Bitstream Vera Sans Mono, Bookman Old Style, Century Schoolbook, Courier, Courier New, Helvetica, Monaco, Palatino, Palatino Linotype, Times, Times New Roman (via javascript) But as a Linux user, those are all mapped by Freetype (some to the same typeface) as many of those are copyright (? encumbered, not freely licensed) fonts: $ for zzz in Arial "Bitstream Vera Sans Mono" "Bookman Old Style" "Century Schoolbook" Courier "Courier New" Helvetica Monaco "Palatino Palatino" Linotype Times "Times New Roman"; do fc-match "$zzz"; done; LiberationSans-Regular.ttf: "Liberation Sans" "Regular" .. 12 more lines of font replacement maps... This website javascript test is measuring a heuristic, giving it a very high score (almost twice as high as anything else, "Hash of canvas fingerprint" is next) but that measurement is patently false compared to the real data. (it also reports no Ad Blocker used and I have uBlock-O fully enabled).
