When Chrominum launches does it say that it's not set as default and than give you the chance to make it the default browser?
It should and if that doesn't work maybe go into the Settings and look there.
Another thing you can try is go to a fresh page and type:"about
:config" and see if you can change the settings to the browser in there.
What DE are you using? Mate? or Cinnamon?

One, you can uninstall Firefox through the Ubuntu Software Center. This should force Ubuntu to set Chromium as your default browser.
