Den f\u00f6rsta testversionen av webbl\u00e4saren FixBrowser har publicerats, som \u00e4r designad f\u00f6r l\u00e5g resursf\u00f6rbrukning och att s\u00e4kerst\u00e4lla sekretess.

Koden \u00e4r skriven i C och FixScript, och distribueras under ZLIB-licensen. F\u00e4rdiga versioner har skapats f\u00f6r Linux (GTK2) och Windows. Det planeras att ta fram versioner f\u00f6r Haiku och macOS 10.6+, samt att skapa versioner f\u00f6r Linux som anv\u00e4nder GTK3\/4. <\/p>\n

F\u00f6r att hantera webbplatser som \u00e4r beroende av JavaScript anv\u00e4nder FixBrowser ett lager som kallas FixProxy, vilket dynamiskt omvandlar s\u00e5dana webbplatser till en version som kan anv\u00e4ndas utan JavaScript. Omvandlingen sker b\u00e5de genom standardmallar och genom fix-behandlare som tar h\u00e4nsyn till specifikationen av specifika webbplatser (det ing\u00e5r fix-behandlare f\u00f6r mer \u00e4n 1200 webbplatser). FixProxy utvecklas som en frist\u00e5ende proxyprocess, oberoende av FixBrowser och kan anv\u00e4ndas med andra webbl\u00e4sare. <\/p>\n

F\u00f6r att hantera CAPTCHA och JavaScript-komponenter, s\u00e5som CloudFlare-kontroller, utan vilka vissa webbplatser inte kan n\u00e5s, planerar man att f\u00f6rbereda ett lager baserat p\u00e5 CEF-ramverket (Chromium Embedded Framework), som kan v\u00e4lja att endast exekvera n\u00f6dv\u00e4ndig JavaScript-kod. Lagret f\u00f6r JavaScript kommer att implementeras som en separat tj\u00e4nst (kan k\u00f6ras b\u00e5de p\u00e5 ditt eget system eller via en offentlig molntj\u00e4nst). <\/p>\n

F\u00f6r att blockera sp\u00e5rning av anv\u00e4ndaraktivitet \u00e4r nedladdning av resurser fr\u00e5n externa v\u00e4rdar f\u00f6rbjuden, och f\u00f6r att till\u00e5ta nedladdning av bilder via inneh\u00e5llsn\u00e4tverk anv\u00e4nds vitlistor. St\u00f6d f\u00f6r HTTPS finns. Det g\u00e5r att ansluta till till\u00e4gg skrivna i spr\u00e5k FixScript. <\/p>\n

Projektet utvecklas av Martin Dvorak fr\u00e5n Tjeckien, som en g\u00e5ng skapade programmeringsspr\u00e5ket FixScript. St\u00f6rre delen av koden f\u00f6r FixBrowser \u00e4r skriven i FixScript, utom de prestandakritiska operationerna och den grundl\u00e4ggande ramverkskoden. Koden i FixScript \u00e4r inb\u00e4ddad i C-kod, och f\u00f6r kompilering anv\u00e4nds en kompilator som levereras i en fil som omfattar cirka 27 000 rader C-kod (800 kB). Spr\u00e5ket liknar C, men anv\u00e4nder dynamisk typning, skr\u00e4ppa avfall och JIT-kompilering. FixBrowser s\u00e4kerst\u00e4ller s\u00e4ker hantering av minne och tr\u00e5dar, samt har inbyggt skydd mot heltals\u00f6verfl\u00f6den. <\/p>\n

Implementeringen av webbl\u00e4sarens motor har kunnat f\u00f6renklas avsev\u00e4rt, eftersom FixBrowser endast utf\u00f6r prim\u00e4r rendering och inte st\u00f6der dynamisk uppdatering av inneh\u00e5ll. N\u00e4r sidan har visats f\u00f6r\u00e4ndras den inte l\u00e4ngre, vilket inneb\u00e4r att man kan klara sig utan s\u00e5dana abstraktioner som DOM (Document Object Model). F\u00f6r n\u00e4rvarande \u00e4r arbetet inriktat p\u00e5 att skapa en HTML-parser som st\u00f6der specifikationerna f\u00f6r HTML5. Den implementering som f\u00f6reslogs i den f\u00f6rsta testversionen t\u00e4cker hittills bara 30% av HTML5-testerna. Grundl\u00e4ggande st\u00f6d f\u00f6r CSS har implementerats.
