Firefox Preview Nightly

Firefox Preview Nightly is the distribution channel for the most recent versions of this well-known Mozilla browser while they're still in beta. This is a great way for developers to test how their apps and sites work with future updates. It's also a great way to try out the latest features.

Although the browser is fully functional, it can be a bit unstable because it's a nightly version. But dealing with a few bugs is worth it if you want to try new features before everyone else.

As a browser, Firefox Preview Nightly offers a wide variety of features, including incognito mode, custom themes, favorites, reading mode, search engine selection, and more. Basically, it has all features you'd expect from any modern browser.

You can also send feedback on the experimental versions of Firefox Preview to its developers so they can fix any bugs before officially releasing it.
