Na spracovanie str\u00e1nok, ktor\u00e9 sa zakladaj\u00fa na JavaScripte, vyu\u017e\u00edva FixBrowser medzi\u010dl\u00e1nok FixProxy, ktor\u00fd za behu konvertuje tak\u00e9to str\u00e1nky na formu, s ktorou sa d\u00e1 pracova\u0165 bez JavaScriptu.

FixProxy sa rozv\u00edja ako samostatn\u00fd proxy proces, nie je pripojen\u00fd k FixBrowser a je vhodn\u00fd na pou\u017eitie s in\u00fdmi prehliada\u010dmi. <\/p>\n

Na spracovanie CAPTCHA a komponentov JavaScriptu, ako s\u00fa kontroly CloudFlare, bez ktor\u00fdch nie je mo\u017en\u00e9 pristupova\u0165 na niektor\u00e9 str\u00e1nky, sa pl\u00e1nuje pripravi\u0165 medzi\u010dl\u00e1nok na b\u00e1ze r\u00e1mca CEF (Chromium Embedded Framework), ktor\u00fd dok\u00e1\u017ee selekt\u00edvne vykon\u00e1va\u0165 len potrebn\u00fd JavaScriptov\u00fd k\u00f3d.

Projekt rozv\u00edja Martin Dvo\u0159\u00e1k z \u010ceska, ktor\u00fd kedysi vytvoril programovac\u00ed jazyk FixScript. V\u00e4\u010d\u0161ina k\u00f3du FixBrowser je nap\u00edsan\u00e1 v FixScripte, s v\u00fdnimkou kritick\u00fdch oper\u00e1ci\u00ed v\u00fdkonnosti a z\u00e1kladn\u00e9ho r\u00e1mca. K\u00f3d v jazyku FixScript je zabudovan\u00fd do k\u00f3du v C, a na zostavenie sa pou\u017e\u00edva kompil\u00e1tor dodan\u00fd v jednom s\u00fabore, ktor\u00fd obsahuje pribli\u017ene 27 tis\u00edc riadkov k\u00f3du v jazyku C (800 kB). Jazyk pripom\u00edna C, ale pou\u017e\u00edva dynamick\u00e9 typovanie, garbage collector a JIT-kompil\u00e1ciu. FixBrowser zabezpe\u010duje bezpe\u010dn\u00fa pr\u00e1cu s pam\u00e4\u0165ou a vl\u00e1knami a tie\u017e obsahuje vstavan\u00fa ochranu pred prete\u010den\u00edm cel\u00fdch \u010d\u00edsel. <\/p>\n

Implement\u00e1ciu prehliada\u010dov\u00e9ho enginu sa podarilo podstatne zjednodu\u0161i\u0165, preto\u017ee FixBrowser vykon\u00e1va len prim\u00e1rne vykreslenie a nepodporuje dynamick\u00e9 aktualiz\u00e1cie obsahu. Po zobrazen\u00ed str\u00e1nky sa u\u017e viac nemen\u00ed, a preto je mo\u017en\u00e9 ob\u00eds\u0165 tak\u00e9 abstrakcie ako DOM (Document Object Model). V s\u00fa\u010dasnosti sa pr\u00e1ca s\u00fastre\u010fuje na vytvorenie HTML pars\u00e9ra, ktor\u00fd podporuje \u0161pecifik\u00e1cie HTML5. Navrhnut\u00e1 implement\u00e1cia v prvom testovacom vydan\u00ed pokr\u00fdva zatia\u013e len 30 % testov HTML5. Bolo implementovan\u00e9 z\u00e1kladn\u00e9 podporu CSS.
