Hi, Usually when there is an unexpected error, logging out of the account on the computer with the issue and then signing back in will resolve this issue. Please try this:

  1. Open up the Firefox Menu and click on Options
  2. Open Sync and remove account
  3. Close and open Firefox
  4. Repeat 1 and sign back in.

Does this resolve the error?

Do you mean that you do not see passwords in the Password Manager?

  • Tools > Options > Security: Passwords: "Saved Passwords" > "Show Passwords"

Try to start Firefox in Safe Mode to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem.

  • Switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance
  • Do NOT click the Reset button on the Safe Mode start window
