Mozilla Firefox is a speedy, secure, and entirely open-source web browser created by the Mozilla Foundation. Built around a mission to support an open and accessible internet, Firefox is committed to user privacy and transparency of choice. Unlike most standard web browsers, Firefox uses minimal user data and provides complete control over tracking, permissions, and cookies through its unique Enhanced Tracking Protection feature.
It offers a streamlined interface and extensive customization options, along with thousands of extensions, themes, and developer tools, catering to both casual users and web professionals. The browser’s privacy mode will automatically block trackers and delete cookies. Features such as Firefox Sync allow users to retrieve their bookmarks, tabs, and passwords from any compatible device securely.
Firefox includes support for all major platforms, including Windows, macOS, Linux, Android, and iOS, allowing users a stress-free experience between both desktop and mobile applications as well. Developers will enjoy its Web Developer Tools, responsive design mode, and JavaScript developer tool.
As reported, more recent versions of Firefox include an improved, faster Quantum engine for better browser speed and responsiveness, improved memory consumption, and overall browser stability with frequently updated features for better compatibility with current web standards. Firefox also features integrated screenshot capabilities, pocket integration (immediately save articles to your pocket account), and a configurable new-tab setup.
