Stopped working in Firefox (56 and 59, desktop and laptop) and Waterfox (56) today. Clicking on toolbar icon shows a white triangle below toolbar icon and nothing pops up - no Vault, no nothing. Windows 8.1 64 bit. Working fine in Chrome, Vivaldi, and Opera latest versions. Removed, reinstalled older version, it worked briefly then back to white triangle below toolbar icon.
Update: Last Pass no longer saves new site logins. I get message that there was an error.
