Web browser

I currently use Firefox, since it’s fast and open source.

Software model

In software, the browser consists of a few key elements. This includes:

• The current tab
  • A JavaScript runtime, including:
    • APIs, like the Document Object Model
  • The webpage
    • A rendering engine
    • The user interface (in HTML and CSS)
    • User input
• Networking protocols (HTTP, etc.)

Sub-pages

• Browser extension
