Epyrus • Get a link in a message to open in PM?

Epyrus 2.1.3. PM 34.2.2 is my default browser in Linux Mint.

I am having trouble opening email links in PM. Let me explain what's happening...

I get an email message with a web link (PM forum reply notification). When I click on the link to open it (open link in browser), it opens a new blank PM window instead of the links web site address. I hope this makes sense...

Perhaps there is a setting that I am missing? Maybe in the about:config?
