I hate the new firefox
Where is the menu bar? why did you remove it? why did you remove the ability to choose among multiple pages to go back to using the back arrow? why did you remove the refresh button? how do tabs work now? this doesn't make any sense.
I have already gone back to firefox 3.5, as the easiest way t get all of these features back. thanks.

You can temporary enable menubar by clicking Alt on your keyboard. Refresh button is now in adressbar on right. For solve your problem I recommend go to support.mozilla.com
Firefox 4 and Firefox 5 look the same. See this:
