Full Changelog

Sync

What's fixed

• Fixes an issue where a stale sync key will be used in cases where a user signs out and signs in to another account. (#1256)

FxA Client

What's new

• Added a new method to help recover from invalid access tokens. (#1244) If the application receives an an authentication exception while using a token
  obtained through FirefoxAccount.getAccessToken, it should:
  • Call FirefoxAccount.clearAccessTokenCache to remove the invalid token from the internal cache.
  • Retry the operation after obtaining fresh access token via FirefoxAccount.getAccessToken.
  • If the retry also fails with an authentication exception, then the user will need to reconnect
    their account via a fresh OAuth flow.
• FirefoxAccount.getProfile now performs the above retry logic automagically. An authentication error while calling getProfile indicates that the user needs to reconnect their account. (#1244
