Firefox connection not working


Suddenly the connection between KeePass and Firefox with Kee stopped working and Kee is showing “OFF”.
I tried the following:

  • Reinstall Kee
  • Reset Firefox profile
  • Change communication port
  • Revoke permission in KeePass addon

Nothing changed but I noticed that after reinstall Kee asked for a new password and KeePass opens the connection window for the password. Also in KeePass the connection is shown as “Connected”.

Any ideas what could be wrong / what I can check?
Firefox console shows this:

Solution found. See here; Kee stopped working in Firefox -- and in Chrome
