Error: "Could not bind socket. Address and port are already in use."

This error is caused by the add-on.

For example, if you launch two clients on the same machine (probably if you are using Password Depot on a terminal server) and receive this error, you must assign to users different port numbers in order to correctly communicate with the browser add-on:

To do so, open the program options by going to Edit -> Options -> Browsers and change the value of the WebSockets port. The same value must then also be set in the browser add-on (within the browser itself).
