Thanks for the reply Martin! I have my Firefox browser settings to clear history (along with cookies, active logons, etc.) when I close the browser. This has never affected my extensions in the past (including Avast passwords), and it still does not affect any other extensions. However, I just tried your suggestion and it had no effect. I closed the browser, re-opened it and the key had turned black again, saying it was not active. I will probably wait until Avast has the problem fixed before I start using Firefox again.
