Before updating to Ubuntu 16.04 LTS, when I clicked on links in Thunderbird emails, the links opened in a new tab in Chrome and waited patiently in the background until I switched to the browser. Since updating, Chrome leaps into the foreground when a link is clicked.
What do I configure to make it behave the way it did before?
