All the flavors of Firefox
Build delightful, secure, performant web content more quickly and easily in a featureful, privacy-respecting browser.
Customize at will
In addition to the wide variety of browsers on offer, our active Add-Ons community provides you with a wide variety of extensions to customize your browser—as well as the support to create your own.
Know what's coming
Firefox Nightly, Developer Edition, and Beta give you the opportunity to experiment features and functionality coming to Firefox in the future, as well as provide you the chance to participate in creating new web technology.
This Firefox has all the latest developer tools in pre-release, including experimental features like the Multi-line Console Editor and WebSocket Inspector.
It has a separate profile and path so you can easily run it alongside Release or Beta.
Preferences are tailored for web developers: Browser and remote debugging are enabled by default, as are the dark theme and developer toolbar button.

Beta (Mobile and Desktop)
Want the latest features, but after they've been fine-tuned in Nightly? Then this is for you.
