Can you please explain a little further? I can't get to understand your problem.

Yet, you can still look this way : -type "about:home" in your address bar. -start firefox from command line "firefox -safe-mode"

That would appear to be the case if it is using something like

• http://start.ubuntu.com/12.04/Google
  • http://shop.ubuntu.com/
  • https://help.ubuntu.com/
  • http://community.ubuntu.com/
  • https://www.google.com/

Some of the links are secure some are not.

Take the problem up with Ubuntu you are using a Firefox build of theirs.

Note you may set more than one page as a homepage. You could include the standard Mozilla homepage. That is obtainable by navigating to about:home
