Если и работает, то догадайся сам..........

Does not work. Have the necessary plugins in keepass desktop app as well

Useless. In KeyPass you can search for passwords by folders or entry names. In this add-on you cannot. You are forced to scroll hundreds of your passwords manually guessing if this might be the account you are looking for. Also if you are visiting some web site where the password is needed, this add-on cannot help you, it just cannot find corresponding entry.
This add-on cost you MUCH MORE time compared to just switching to KeyPass and searching entry there.

Unistall this useless add-on.

Nothing changed or improvement so far...

I'll wait for a new version of KeeFox.

I was not able to login to a single website with it on FF55. I hope Keefox updates.

Por mas que le busco una utilidad a esto, no se la encuentro ...
