Mozilla’s Test Pilot program for Firefox has long been the organization’s way to trial some of its more experimental ideas for new browser features. Now it’s expanding this program to include mobile apps, too, with the launch Firefox Lockbox, of a password manager for iOS, and Notes by Firefox, a note-taking app for Android.

Both apps have a connection to Firefox (hence their names), but we’re not talking about Firefox plugins here. These are stand-alone apps that sync with Firefox on the desktop and mobile and share its branding.
