What is Mozilla Firefox?

Mozilla Firefox is a free and open-source web browser that is known for its stability, speed, and privacy features while surfing the internet. The web browser has a modern interface and runs on the Gecko engine, which allows for fast tab loading and instantaneous conversion of HTML code into a visual page.

The program is the world's second-most popular web browser and offers a plethora of add-ons, which can be used to customize the browser to suit individual needs. Firefox can be downloaded for desktop or mobile devices.


  • Extensions - developers have created a "constructor" where each user can independently add necessary elements;
  • Library - contains bookmarks, browsing history, synchronized tabs - all in one place;
  • Personalization - customize the toolbar, menu, and browser themes to suit your needs;
  • Performance - the "light" engine, powerful program core, flexibility, and expandability of the browser ensure fast and enjoyable internet browsing.

How to Use

Upon launch, users are greeted with the initial window where they can enable synchronization, subscribe to notifications about data leaks from Firefox Monitor, or open a private window for secure browsing. A search bar and standard tabs are located below. The application can be used in its standard configuration.

To customize the program to suit individual needs, users can click the settings button in the upper right corner, where they can find recommended extensions, plugins, themes, add-on stores, and a flexible personalization system. Using these functions, users can "build" a unique browser suitable for their specific needs.


  • Automatic updates;
  • Confidentiality;
  • Expandability;
  • "Master password" encrypts all other passwords;
  • Content is displayed before the entire page is loaded.
