Today, 5/5/19 firefox rendered lastpass inoperable and it was no longer downloadable from the add-on site. I'm not using Firefox until you renable use of Lastpass.

Sorry, there is a Firefox 66.0.4 update available to fix this problem. See: Update Firefox to the latest release.

Background: a certificate required to verify add-on signatures expired, and all versions of Firefox need a new certificate installed.
