Mozilla Firefox Beta158.0b3

Mozilla Firefox Beta lets Mac users browse the internet, open online services, and try upcoming Firefox capabilities before they reach a final release. It is a desktop browser in the Internet & Browsers category, aimed at people who want to explore future Firefox releases for desktop, Android, and iOS.

Version 158.0b3 is intended for testing and development rather than everyday stability, so users can examine new behavior and report problems before the corresponding changes reach a stable environment. By default, the browser sends data to Mozilla and sometimes its partners to help investigate issues and evaluate ideas. Users can also submit feedback that guides final adjustments to performance and functionality.

Firefox Beta runs on macOS 10.15 or later and supports both Intel and Apple Silicon Macs. It is offered under a freeware license, and its English (US) release is one of the available language and platform variants. The program suits Mac users who are comfortable evaluating pre-release software and helping refine the browser through practical use and feedback.
