Firefox is a free and open source web browser developed by the Mozilla Foundation. Its origin dates back to 2002, when it was launched as a more secure and customizable alternative to the dominant browsers at that time.

The name "Firefox" refers to the red panda, a mammal that lives in the Himalayas and southern China. This name was chosen to reflect Mozilla's policy of preserving the diversity and health of the web, just as conservation efforts seek to protect endangered species.


Firefox is distinguished from other browsers by several unique features:

  • Enhanced privacy: Firefox places a heavy emphasis on user privacy and offers several security features, such as tracker blocking, phishing protection, and private browsing option.
  • Personalization: With Firefox, users can customize their browsing experience with extensions and themes. They can also adjust browser settings to suit their needs and preferences.
  • Performance: Firefox uses a rendering engine called Gecko, which is regularly updated to improve performance and compatibility with new web technologies.
  • Cross-platform support: Firefox is compatible with a wide range of operating systems, including Windows, macOS, Linux, Android, and iOS.
