Firefox user interface is built on XPTool kit.Expat for XML Parser, Spider monkey for java script interpreter etc. Software used to implement the Firefox modules is mentioned in the figure. But in the conceptual they are integrated into Gecko. In the reference architecture there are two layers for Browser engine and rendering engine. In the reference architecture, the user interface connects to the Data Persistence component also. It is not connected to other subcomponents. In the conceptual architecture user interface only builds on gecko. But there are two differences between them. We can see that Firefox architecture is largely same to the reference architecture.Display Backend component It provides primitive drawing and windowing methods that are host operating system dependent. Handles all aspects of Internet communication and security. Networking component Handle protocols as HTTP and FTP. Data Persistence component Manages user data such as bookmarks and preferences.

Basically browser is a app to retrieve present travers info/resources on HTML is passed to the browser's layout engine to be transformed from markup to an interactive document. First we’ll look at a general browser and identify its characteristics.Our objective is to compare the 2 browsers. Then the developers added features and released updates under the name of chromium. This was initially the same as the Chrome but Google gave out the source code of chrome for developers and the name of the project was chromium. Since the last decade its a paradise for application developers. Firefox is a well known browser for using extensions.Networking Subsystem of Security Model of Multiple Processes for same Application.Watch Audio, Video, Images and other non-HTML.Software application for retrieving, presenting,Īnd traversing information resources on the ![]()
