I put this in as a support ticket last October. I was told they were working on it for version 62, and the only way I'd know if it was fixed was to go into FireFox and try to find it again. I was also told I might as well use the FireFox password manager. I thought that was a fairly poor answer.
It is now January 2019. I just went into Firefox and still can't find the Webroot Password Manager as an extension. FireFox is up to version 64. Has anyone heard anything about this?

Webroot was reporting the new Password Manager will be out this month or next month (February). They are working with LastPass for the newest Password Manager for Webroot.
