Mozilla Company advarer<\/a><\/noindex> om opkomsten af masse- problemer<\/a><\/noindex> med till\u00e6g til Firefox. Alle brugere af browseren oplevede, at till\u00e6ggene blev blokeret p\u00e5 grund af udl\u00f8bet af den digitale underskrifts certifikat. Desuden bem\u00e6rkes, at det ikke er muligt at installere nye till\u00e6g fra det officielle katalog AMO<\/a><\/noindex> (addons.mozilla.org). <\/p>\n

Der er endnu ikke fundet en l\u00f8sning p\u00e5 den opst\u00e5ede situation ikke fundet<\/a><\/noindex>, udviklerne hos Mozilla overvejer mulige l\u00f8sninger og har indtil videre kun bekr\u00e6ftet den opst\u00e5ede situation. Det n\u00e6vnes kun, at till\u00e6ggene blev inaktive efter kl. 00:00 (UTC) den 4. maj. Certifikatet skulle v\u00e6re blevet opdateret for en uge siden, men af en eller anden grund skete det ikke, og denne kendsgerning gik ubem\u00e6rket hen. Nu vises der et advarsel efter et par minutter efter browserens opstart om, at till\u00e6ggene er deaktiveret p\u00e5 grund af problemer med den digitale underskrift, og till\u00e6ggene forsvinder fra listen. Kontrollen af den digitale underskrift foretages en gang om dagen eller efter genstart af browseren, s\u00e5 i l\u00e6nge k\u00f8rte forekomster af Firefox kan till\u00e6ggene deaktiveres ikke straks.<\/p>\n

\"Alle<\/a><\/noindex><\/center><\/p>\n

Som en midlertidig l\u00f8sning for at genoptage adgangen til tilf\u00f8jelser kan Linux-brugere deaktivere kontrol af digitale signaturer ved at indstille variablen 'xpinstall.signatures.required' i about:config til 'false'. Denne metode fungerer kun i Linux og Android for stabile og beta-versioner; for Windows og macOS er s\u00e5danne manipulationer kun mulige i natbuilds og udviklerversionen (Developer Edition). Som et alternativ kan man ogs\u00e5 \u00e6ndre systemklokkens tid til et tidspunkt f\u00f8r udl\u00f8bet af certifikatet, hvilket s\u00e5 ville genskabe muligheden for at installere tilf\u00f8jelser fra AMO-kataloget, men den allerede installerede deaktivering vil ikke blive fjernet.<\/p>\n

Vi minder om, at den obligatoriske kontrol af Firefoxtill\u00e6g ved hj\u00e6lp af digitale underskrifter blev indf\u00f8rt<\/a><\/noindex> i april 2016. If\u00f8lge Mozilla tillader kontrollen af den digitale underskrift at blokere distributionen af skadelige og spionerende till\u00e6g. Nogle till\u00e6gsudviklere er ikke enige<\/a><\/noindex> med denne holdning mener de, at mekanismen for obligatorisk kontrol ved hj\u00e6lp af digital signatur blot skaber vanskeligheder for udviklere og f\u00f8rer til en forl\u00e6ngelse af tiden for at levere rettelser til brugerne, uden at det har nogen indflydelse p\u00e5 sikkerheden. Der er mange trivielle og \u00e5benlyse metoder<\/a><\/noindex> til at omg\u00e5 systemet for automatisk kontrol af udvidelser, som g\u00f8r det muligt at inds\u00e6tte skadelig kode uset, for eksempel gennem dannelsen af operationer on-the-fly ved at sammenk\u00e6de flere strenge med efterf\u00f8lgende udf\u00f8relse af den resulterende streng ved hj\u00e6lp af eval. Mozillas holdning reduceres<\/a><\/noindex> til, at de fleste forfattere af skadelige udvidelser er dovne og ikke vil benytte sig af s\u00e5danne teknikker til at skjule skadelig aktivitet. <\/p>\n

Supplerende: Mozilla-udviklere meldte<\/a><\/noindex> om begyndelsen af testningen af en rettelse, som hvis den bliver testet positivt, snart vil blive sendt til brugerne (beslutningen om at anvende den foresl\u00e5ede rettelse er endnu ikke truffet). Indtil rettelsen tr\u00e6der i kraft, er dannelsen af digitale signaturer for nye udvidelser deaktiveret.<\/p>\n
