[lubuntu] Firefox nowhere to be found in Lubuntu-desktop

view story

http://ubuntuforums.org – I have just installed lubuntu-desktop on top of ubuntu 12.04. I understand that chromium is the default browser in lubuntu but I was expecting Firefox to show up under the Internet menu. It is installed in my computer, and it shows in the Lubuntu Software Center under installed applications but I cannot find it anywhere. How do I have it show up on the Internet menu? (Hardware)
