Chrome 90 versioonis Linuxile see meetod ei t\u00f6\u00f6tanud ja brauser n\u00e4itas k\u00f5igi kontrollimise katsete puhul t\u00fc\u00fcpilist tegevuse kinnitamise dialooge (Windowsi ja macOS-i jaoks t\u00f6\u00f6tab see meetod). Firefox 88 versioonis Linuxile tuvastas skript nii tavare\u017eiimis kui ka inkognito re\u017eiimis, et on installitud lisarakendusi, ja tuvastamise t\u00e4psus hinnati 99,87% (35 sarnast vasteid 26 000 l\u00e4biviidud testist). Tor Brauseris, mis t\u00f6\u00f6tas samas s\u00fcsteemis, genereeriti ID, mis kattus Firefoxi testiga. <\/p>\n

Huvitav, et Tor Brauseri t\u00e4iendav kaitse m\u00e4ngis halba nalja ja muutus v\u00f5imaluseks tuvastada kasutajat m\u00e4rkamatult. Kuna Tor Brauseris on v\u00e4liste t\u00f6\u00f6tlejate kinnituse dialoogid v\u00e4lja l\u00fclitatud, sai kontrollimisettepanekuid avada iframe'is, mitte h\u00fcpikaknas (puuduvuse ja olemasolu t\u00f6\u00f6tlejate eristamiseks kasutatakse seda, et same-origin reeglid blokeerivad juurdep\u00e4\u00e4su vigadega lehtedele ja lubavad lehtedele about:blank). Tulenevalt sp\u00e4mmi kaitsmisest v\u00f5tab Tor Brauseris kontrollimine oluliselt rohkem aega (10 sekundit rakenduse kohta).
