Den f\u00f8rste testudgave af webbrowseren FixBrowser er blevet offentliggjort, designet til lavt ressourceforbrug og beskyttelse af privatliv. Browseren udvikles fra bunden og underst\u00f8tter principielt ikke k\u00f8rsel af JavaScript, men g\u00f8r det muligt at arbejde med websider, der er afh\u00e6ngige af JavaScript. Koden er skrevet i C og FixScript og distribueres under ZLIB-licensen. F\u00e6rdige versioner er lavet til Linux (GTK2) og Windows. Der planl\u00e6gges at lave versioner til Haiku og macOS 10.6+, samt at skabe versioner for Linux, der bruger GTK3\/4. <\/p>\n

For at arbejde med websider, der er afh\u00e6ngige af JavaScript, anvendes FixProxy i FixBrowser, som i realtid omdanner disse sider til en form, der kan arbejdes med uden JavaScript. Omdannelsen sker b\u00e5de efter typiske skabeloner og ved hj\u00e6lp af fix-h\u00e5ndterere, der tager h\u00f8jde for de specifikke egenskaber ved bestemte websteder (der er inkluderet fix-h\u00e5ndterere for mere end 1200 websteder). FixProxy udvikles som en separat proxy-proces, der ikke er bundet til FixBrowser og kan bruges med andre browsere. <\/p>\n

Det bem\u00e6rkes, at der kun kr\u00e6ves sm\u00e5 \u00e6ndringer for at vise de fleste hjemmesider uden JavaScript. Desuden anvendes der p\u00e5 mange hjemmesider ensartede teknologier til dynamisk generering af indhold, hvilket muligg\u00f8r brugen af generiske fix-h\u00e5ndterere til deres rendering. For eksempel kan man bruge universelle fix-h\u00e5ndterere til websteder baseret p\u00e5 WordPress-motoren og fora p\u00e5 Disqus-platformen. Det er ogs\u00e5 muligt at oprette h\u00e5ndterere til websteder, der dynamisk renderer indhold \u2014 for eksempel til at vise en liste over kommentarer, som oprindeligt indl\u00e6ses dynamisk ved hj\u00e6lp af JavaScript; en fix-h\u00e5ndterer henter direkte data i JSON-format og danner HTML ud fra disse data. <\/p>\n

For at h\u00e5ndtere CAPTCHA og JavaScript-komponenter som CloudFlare-kontroller, der er n\u00f8dvendige for at f\u00e5 adgang til visse websteder, planl\u00e6gger man at forberede et lag baseret p\u00e5 CEF (Chromium Embedded Framework), der kan k\u00f8re kun den n\u00f8dvendige JavaScript-kode selektivt. JavaScript-laget vil blive implementeret som en separat tjeneste (man kan k\u00f8re det p\u00e5 sit eget system eller bruge en offentlig cloud-tjeneste). <\/p>\n

For blocking user activity tracking, downloading resources from third-party hosts is prohibited, and to allow image loading via content delivery networks, whitelists are applied. HTTPS support is available. It is possible to connect extensions written in FixScript. <\/p>\n

The project is developed by Martin Dvorak from the Czech Republic, who once created the FixScript programming language. Most of the FixBrowser code is written in FixScript, except for performance-critical operations and the basic framework. The FixScript code is embedded in C code, and a compiler is used for building, provided in a single file containing approximately 27 thousand lines of C code (800 KB). The language resembles C but uses dynamic typing, a garbage collector, and JIT compilation. FixBrowser ensures safe memory and thread operations and has built-in protection against integer overflows. <\/p>\n

Implementing the browser engine has been significantly simplified, as FixBrowser only performs the primary rendering and does not support dynamic content updates. Once the page is displayed, it does not change, which means that abstractions like the DOM (Document Object Model) can be omitted. Currently, work is focused on creating an HTML parser that supports HTML5 specifications. The implementation proposed in the first test release covers only 30% of HTML5 tests so far. Basic support for CSS has been implemented.
