Наслагване на html във Firefox?

Лесно е да наслагвате xul UI, когато правите добавка за Firefox, но какво ще кажете за html файловете?

Струва ми се странно, че части от Mozilla използват това, като PDF.js четеца. Има ли някаква полза от HTML пред по-естествения и гъвкав XUL? Какво ще стане, ако искате да добавите функции към pdf четеца, който е html файл в pdfjs/content/web/viewer.html:

Обективно не е по-естествено и гъвкаво и няма да можете да споделяте какъвто и да е код със съществуващи JS/HTML или DOM библиотеки или да накарате вашата да работи на друг браузър. - Benjamin Gruenbaum 08.02.2014

comment

Имате право, но XUL е единственият уеб език, който ви позволява да създавате реално изглеждащи естествено приложения или прозорци и има естествени тагове vbox, hbox и атрибут flex, който ви позволява да създавате гъвкав потребителски интерфейс, без да научавате за експертно ниво HTML float, display-block, margin, width/height проценти + пиксели (които не се смесват) и т.н. Неработенето в други браузъри е по вина на Firefox и всъщност трябва да работи в много от най-популярните браузъри Firefox, Flock, Seamonkey и др. - NoBugs 09.02.2014

Не е нужно да ме убеждавате, че HTML се използва тук за приложения, а не за документи, за което е създаден. Екосистемата обаче е огромна. - Benjamin Gruenbaum 09.02.2014

В момента не е възможно наслагване на html файлове. Не виждам защо това не може да бъде приложено, но ще отнеме известно време и това е проблем с нисък приоритет, защото това не е идея, която е естествена за мрежата.
