A fost publicat primul num\u0103r de test al browserului web FixBrowser, conceput pentru a consuma pu\u021bine resurse \u0219i pentru a asigura confiden\u021bialitatea. Browserul se dezvolt\u0103 de la zero \u0219i nu suport\u0103 \u00een mod fundamental execu\u021bia JavaScript, dar permite accesarea site-urilor care depind de JavaScript. Codul este scris \u00een limbajele C \u0219i FixScript, \u0219i este distribuit sub licen\u021ba ZLIB. Versiunile finale sunt disponibile pentru Linux (GTK2) \u0219i Windows. Exist\u0103 planuri de a crea versiuni pentru Haiku \u0219i macOS 10.6+, precum \u0219i pentru Linux, utiliz\u00e2nd GTK3\/4. <\/p>\n

Pentru a lucra cu site-uri care depind de JavaScript, FixBrowser folose\u0219te un strat FixProxy, care transform\u0103 \u00een timp real aceste site-uri \u00eentr-o prezentare care poate fi utilizat\u0103 f\u0103r\u0103 JavaScript. Transformarea se face at\u00e2t prin \u0219abloane tipice, c\u00e2t \u0219i prin fix-handleri, care \u021bin cont de specificul site-urilor particulare (included sunt fix-handleri pentru mai mult de 1200 de site-uri). FixProxy se dezvolt\u0103 ca un proces proxy separat, f\u0103r\u0103 leg\u0103tur\u0103 cu FixBrowser, fiind potrivit pentru utilizarea cu alte browsere. <\/p>\n

Se observ\u0103 c\u0103 pentru a afi\u0219a majoritatea site-urilor f\u0103r\u0103 JavaScript sunt necesare doar modific\u0103ri minore. \u00cen plus, multe site-uri folosesc tehnologii uniforme pentru generarea dinamic\u0103 a con\u021binutului, ceea ce permite aplicarea de handleri fix standardiza\u021bi pentru redarea lor. De exemplu, pot fi utilizate handleri fix universali pentru site-uri bazate pe motorul WordPress \u0219i forumuri pe platforma Disqus. Este posibil s\u0103 se creeze handleri \u0219i pentru site-uri care genereaz\u0103 dinamic con\u021binut \u2013 de exemplu, pentru afi\u0219area unei liste de comentarii, ini\u021bial \u00eenc\u0103rcate dinamic cu ajutorul JavaScript, handlerul fix \u00eencarc\u0103 direct datele \u00een format JSON \u0219i \u00ee\u0219i formeaz\u0103 singur HTML-ul pe baza acestora. <\/p>\n

Pentru a gestiona captcha \u0219i componentele JavaScript, cum ar fi verific\u0103rile CloudFlare, f\u0103r\u0103 de care accesul pe anumite site-uri nu este posibil, se pl\u0103nuie\u0219te preg\u0103tirea unui strat bazat pe frameworkul CEF (Chromium Embedded Framework), care va putea executa selectiv doar codul JavaScript necesar. Strat pentru JavaScript va fi implementat ca un serviciu separat (poate fi lansat at\u00e2t pe sistemul propriu, c\u00e2t \u0219i utilizat un serviciu cloud accesibil publicului). <\/p>\n

Pentru a bloca urm\u0103rirea activit\u0103\u021bii utilizatorului, \u00eenc\u0103rcarea resurselor de pe gazde externe este interzis\u0103, iar pentru a permite \u00eenc\u0103rcarea imaginilor prin re\u021bele de livrare a con\u021binutului se aplic\u0103 liste albe. Suport pentru HTTPS este disponibil. Este posibil\u0103 conectarea extensiilor scrise \u00een limbajul FixScript. <\/p>\n

Proiectul este dezvoltat de Martin Dvorak din Cehia, care a creat limbajul de programare FixScript. Majoritatea codului FixBrowser este scris \u00een limbajul FixScript, cu excep\u021bia opera\u021biunilor critice pentru performan\u021b\u0103 \u0219i a structurii de baz\u0103. Codul \u00een FixScript este integrat \u00een codul C, iar pentru compilare se folose\u0219te un compilator furnizat \u00eentr-un singur fi\u0219ier, care include aproximativ 27 de mii de linii de cod \u00een limbajul C (800 KB). Limbajul aminte\u0219te de C, dar folose\u0219te tipizare dinamic\u0103, colector de gunoi \u0219i compilare JIT. FixBrowser asigur\u0103 o utilizare sigur\u0103 a memoriei \u0219i a firelor, av\u00e2nd \u00een plus o protec\u021bie \u00eencorporat\u0103 \u00eempotriva dep\u0103\u0219irilor de \u00eentregi. <\/p>\n

Implementarea motorului de browser a fost semnificativ simplificat\u0103, deoarece FixBrowser realizeaz\u0103 doar randarea ini\u021bial\u0103 \u0219i nu suport\u0103 actualizarea dinamic\u0103 a con\u021binutului. Dup\u0103 ce pagina este afi\u0219at\u0103, aceasta nu se mai schimb\u0103, prin urmare, se poate evita utilizarea unor abstrac\u021bii precum DOM (Modelul de Obiect Document). \u00cen prezent, activitatea se concentreaz\u0103 pe crearea unui parser HTML care s\u0103 suporte specifica\u021biile HTML5. Implementarea propus\u0103 \u00een prima versiune de test acoper\u0103 deocamdat\u0103 doar 30% din testele HTML5. Suportul de baz\u0103 pentru CSS a fost implementat.
