Question
Firefox is not detecting the Client Agent and is asking me to install it again even though it is already running. How do I fix this?
Answer
In order to resolve this issue you will need to add the client agent
In the URL bar, type in the following address: https://127.0.0.1:56209/

From there, click on Confirm Security Exception

After doing this, you will now be able to use the Clipboard Manager/Paste+ with Firefox.
