Firefox 4.0 is not compatible with 3.6.x. Is there a hidden compatibility mode?

I installed Firefox 4.0 and attempted to use it for three days. I found the new user interface to be significantly different from version 3.6. It was so clumsy to use that I re-installed 3.6. Is there a compatibility mode for 4.0 that preserves the 3.6 interface? If not, why not?

If you do not like the new appearance of Firefox 4 then you can change some setting to restore the Firefox 3 appearance.

You can right click the orange Firefox button to open the toolbar menu.

  • Click the Menu Bar entry to make the Menu Bar visible.
  • Click "Tabs on Top" to remove the check mark and place the Tab Bar at its original position just above the browser window.
