[xubuntu-users] click on a link

[Norman Silverstone]

I have two browsers installed, Google Chrome and Firefox with Google 
Chrome set as default. When I click on the icon in the bottom panel, 
Google Chrome duly appears. In Settings Manager, preferred Applications 
the Web Browser is set to google-chrome yet, when I click on a link in 
an email for example, Firefox loads. I do not want Firefox so, please, 
what am I doing wrong?
