The beta builds of software can be unstable and aren’t recommended for daily use, however, they’re often the only way that users can test features that are still in development. Mozilla came up with a different way for its Firefox browser called Test Pilot. The feature lets users on stable builds of the browser test experimental features that it’s working on. Mozilla has now announced that it’s expanding Test Pilot to the mobile with two new experimental features.

Firefox Lockbox is the first new feature that is available to Firefox users on iOS through Test Pilot. It’s a password manager which enables the browser to automatically log in to any site for which the user has saved the password. It also works with both Touch ID and Face ID. The Lockbox feature is only available on iOS, though.

Since Test Pilot has also been expanded to Android, the next experimental feature is available on Google’s platform exclusively. Notes by Firefox lets users write down their thoughts directly from within the browser. The notes are synced across platforms so they can view notes they wrote in Firefox on the web later on their Android smartphone as well. All notes are end-to-end encrypted.

Interested users can participate in the Test Pilot program, they just need a Firefox account and Firefox Sync for these features to run properly.
