How Does Firefox Work?

Firefox is a web browser that is made by Mozilla. It is free and open-source software. The code for Firefox is written in C++, and it uses the Gecko layout engine to render web pages.

The first version of Firefox was released in 2004, and it has been widely popular since then. More than half a billion people use Firefox every day. 

Firefox generally starts up quickly and uses less memory than other browsers. It also offers many features that are well-suited for power users, such as tabbed browsing, live bookmarking, support for extensions, and more. 

When you type a URL into the address bar of Firefox, the browser contacts a DNS server to find out the IP address of the website you’re trying to visit. Once it has the IP address, it connects to the website’s server and requests the page you’re trying to load. The server then sends the page back to Firefox, which displays it on your screen.

As a result, you can browse the web with confidence knowing that your computer is safe from harm.
