  　・See if any of your saved passwords may have been exposed in a data breach
  　To view your dashboard, type about:protections into the address bar, or select “Protections Dashboard” from the main menu.
  ・Because we know people try to fix problems by reinstalling Firefox when a simple refresh is more likely to solve the issue, we’ve added a Refresh button to the Uninstaller.
  ・With this release, your screen saver will no longer interrupt WebRTC calls on Firefox, making conference and video calling in Firefox better.
