Firefox Beta is the build for those who like a little bit of jeopardy, but who don’t want to risk everything by trying out Firefox Developer, the early alpha build of Firefox. Firefox Beta gives you a sneak peek at the next version of Firefox six weeks ahead of its final release, offering a relatively stable build that’s not quite ready for primetime, but still pretty solid.

Whereas Firefox Developer installs as a completely separate application alongside your existing Firefox installation, Firebox Beta will replace the stable build. Should you subsequently wish to go back to the safer version, you’ll need to manually download the stable version and install it over the top of the beta build.

Confirm which build you have by selecting About Firefox from the Firefox menu or button (it’s inside the Help menu if using the Firefox button).

Firefox 57 is a major update as it will become the "next generation" Firefox, Quantum, due for launch 14 November 2017. This will bring a new UI and much more. But, if you're impatient, you can try it right now with Firefox 57 Beta.

Firefox 57 is now in the Beta channel. New features include:

- Firefox is getting a major Visual Redesign (Photon project) activated on the Nightly channel and which will ship with Firefox 57 on the release channel.
- Added support for Date/Time input
- Accessibility indicator will now appear in the title bar of the window when Accessibility services are enabled
- Allow users to manage the site data


Version 54 includes enhanced protection against malware downloads and more.
