Kee fails on Firefox 63.0.3 (64 bit)

Always get the following message when I try to directly connect to a KeePass entry with Firefox Kee. Also, automatic login does NOT work. It doesn’t insert the actual password that is in KeePass. If I cut and paste directly from KeePass the login works fine. But the Kee auto login fails evey time.

Firefox can’t find the file at moz-extension://f7acb447-0bf5-4d60-be4e-2325cd5ac54a/popup/www.kmart.com.

Can you explain more about what you mean?

What do you do to trigger this error? Are you sure it is from Kee? moz-extension://f7acb447-0bf5-4d60-be4e-2325cd5ac54a could be any extension on your Firefox so that’s worth checking.
