En korrekturversion av Firefox 97.0.2 och 91.6.1 har sl\u00e4ppts f\u00f6r att \u00e5tg\u00e4rda tv\u00e5 s\u00e5rbarheter som har blivit klassificerade som kritiska problem. S\u00e5rbarheterna m\u00f6jligg\u00f6r att man kan kringg\u00e5 sandbox-isoleringen och uppn\u00e5 k\u00f6rning av godtycklig kod med webbl\u00e4sarens beh\u00f6righeter vid hantering av s\u00e4rskilt utformat inneh\u00e5ll.

Det rekommenderas att alla anv\u00e4ndare av webbl\u00e4sare baserade p\u00e5 Firefox-motorn omedelbart installerar uppdateringar. Anv\u00e4ndare av Tor Browser, som \u00e4r baserat p\u00e5 ESR-grenen av Firefox 91, b\u00f6r vara s\u00e4rskilt uppm\u00e4rksamma p\u00e5 att installera uppdateringar, eftersom s\u00e5rbarheterna kan leda till inte bara systemkompromiss utan ocks\u00e5 till de-anonimisering av anv\u00e4ndaren.
