I l\u00f8pet av den nye to uker lange utgivelsessyklusen har Firefox 159 blitt sendt til beta-testing, med utgivelse planlagt til 27. oktober. <\/p>\n<p>De viktigste nyhetene i Firefox 158 (1, 2, 3):<\/p>\n<ul>\n<li class=\"l\"> St\u00f8tte for dekoding av bilder i JPEG XL-format er aktivert som standard. MIME-typen 'image\/jxl' er lagt til i HTTP-headeren Accept. Som i Chrome er implementeringen av JPEG-XL i Firefox basert p\u00e5 biblioteken jxl-rs, skrevet i Rust. JPEG XL gj\u00f8r det mulig \u00e5 redusere filst\u00f8rrelsen med 30-50 % sammenlignet med JPEG-bilder av lik kvalitet. Blant de st\u00f8ttede avanserte funksjonene: HDR, animasjon, gjennomsiktighet, progressiv lasting, jevn kvalitetsforringelse ved lavere bitrate, tapsfri JPEG-komprimering, st\u00f8tte for opptil 4099 kanaler og et bredt spekter av farge dybder.\n<li class=\"l\"> Det er lagt til muligheten for automatisk utfylling av skjemaer i 'Smart Window'-modus, som gir et eget interaksjonsrom med AI. N\u00e5r du klikker p\u00e5 et felt i webskjemaet, foresl\u00e5r AI alternativer laget med hensyn til \u00e5pne faner og tidligere lagrede autofyll-data. Muligheten er aktivert for en del brukere.\n<li class=\"l\"> I bakgrunnsinnstillingene p\u00e5 siden som vises n\u00e5r en ny fane \u00e5pnes, er det n\u00e5 mulig \u00e5 lagre historikken over alle lastede bakgrunnsbilder, ikke bare det nyeste bildet. Alle bildene valgt av brukeren kan sees i seksjonen 'Dine bilder'.\n<p><center><img decoding=\"async\" src=\"\/wp-content\/uploads\/2026\/10\/c05257d1050056ca3063cd5e52795578.png\" style=\"display:block;margin: 0 auto;\" \/><\/center><\/p>\n<li class=\"l\"> Lagring av sider i PDF-format og utskrift p\u00e5 Linux og macOS er blitt forbedret. Problemer med PDF-rendering, slik som ignorering av matematiske symboler, er l\u00f8st.\n<li class=\"l\"> Oversettelse til belarusisk spr\u00e5k er blitt implementert.\n<li class=\"l\"> Gjennom bruk av sub-piksel posisjonering av rulling (uten avrunding til hele skjermpikser) er rulling blitt mer jevn p\u00e5 skjermer med h\u00f8y piksel tetthet eller n\u00e5r siden er zoomet.\n<li class=\"l\"> I CSS-funksjonen calc() er st\u00f8tte for typebasert aritmetikk lagt til, noe som gj\u00f8r det mulig \u00e5 utf\u00f8re aritmetiske operasjoner med hensyn til angitte enheter, for eksempel calc(50vw + 2rem), calc(1000px \/ 2) eller calc(40deg + 2rad).\n<li class=\"l\"> I API Notification og metoden ServiceWorkerRegistration.showNotification() er en ny navigasjonsalternativ lagt til, som definerer URL-en for navigering etter klikk p\u00e5 varslingen.\n<li class=\"l\"> For inndatamaskiner med attributtet 'autocomplete='webauthn'' er det implementert visning av et popup-vindu for passordl\u00f8s autentisering via fingeravtrykk eller ansikt.\n<li class=\"l\"> Det er lagt til st\u00f8tte for verdien 'cache' i egenskapen PerformanceResourceTiming.deliveryType for \u00e5 identifisere ressurser hentet fra cache.\n<li class=\"l\"> Support for the WebGL extension EXT_polygon_offset_clamp has been added.\n<li class=\"l\"> The Firefox version for Android now allows the tab list panel to be placed at the top or bottom of the window.\n<li class=\"l\"> A new edition of Firefox Enterprise has been created, the features of which are described in a separate review.\n<\/ul>\n<p>In addition to new features and bug fixes, Firefox 158 addresses 77 vulnerabilities, with 30 of them classified as high risk. Most vulnerabilities are caused by memory handling issues, such as buffer overflows and accessing already freed memory areas.
