Mozilla Firefox is a widely used open-source web browser that is compliant with web standards set by the W3C. It is comparable to other major browsers but is considered to be the most customizable.

Firefox is available for Windows, macOS, and Linux, and also has a mobile version that is available for Android and iOS. It has many features standard among popular browsers like tabbed browsing, built-in spell checking, and password management. It also has a large developer community and provides many developer tools and support.

The web browser boasts a variety of security features, such as enhanced tracking protection that shows you the number of data-collecting trackers being blocked. Firefox Lockwise allows you to sync passwords used in the browser across all your devices and Firefox Monitor notifies you if your confidential information has been compromised by a company's data breach.

Mozilla Firefox is a great web browser for users who like customizing their web browsing experience and are looking for a secure browsing experience. It is one of the best web browsers available and a great alternative for those who don't want to use Google Chrome.
