Mozilla Firefox

[|Mozilla Firefox Developer Center]Mozilla Firefox is a free web browser for Windows, Linux and macOS, in which the latest stable version is 92.0.1. The latest beta release (as of September 23, 2021) is 93.0, and the latest Nightly release is 94.0a1.

History
Firefox is a direct descendant of the Mozilla Suite's browser, which in turn was a rewrite of the original Netscape code. It was created because most people did not need or want the bloat such as an email client or HTML editor in their browser.
