Firefox Accounts lets you access Mozilla Services on any device with Firefox or Firefox OS. All you need to create a Firefox Account is an email address and a password.

What services can I use with Firefox Accounts?

The following Mozilla Services are available now:

1. Firefox Sync: Access your browsing data, like bookmarks, history, passwords and open tabs on multiple devices with just a Firefox Accounts login.
2. Firefox Marketplace: Purchase paid apps safely, add and track app reviews, and access your app library on all your devices. (Note: Free apps do not require a Firefox Account.)

Use Firefox Accounts to access the following services in the near future:

1. WebRTC: A Firefox Account is not required to communicate with your friends using Firefox's upcoming video and voice chat feature, but it gives you the option to create a contact list.
2. Find My Device: Find, lock or erase a lost Firefox OS device from your computer.
