Hi, is the problem just in the content area -- the page changed -- or is the problem in the toolbar area -- the toolbars disappeared?

To change your home page (the page in the content area), see:

• Selecting the page: How to set the home page
• Modifying sections of the built-in Firefox Home / new tab page: Customize your New Tab page to hide or display content
• Modifying individual items on the Firefox Home / new tab page: Customize items on your Firefox New Tab page

If the toolbars disappeared, perhaps the browser is in full screen mode? You could try pressing Esc or Ctrl+F, or sliding the mouse up to the top of the screen and seeing whether the toolbars roll down.

Is this about opening an external link in the default browser (Firefox) ?

You can check the connection settings.

• Settings -> General -> Network: Connection -> Settings

If you do not need to use a proxy to connect to internet, select "No Proxy" if "Use the system proxy settings" or one of the of the others do not work properly.

See "Firefox connection settings":
