If you’re a Firefox user in Ubuntu 11.04, there’s a good chance that you don’t have the default menu button back. This is because Ubuntu changed the way it handles menu buttons in that release. If you’re not sure how to restore the default menu button, here’s how:

  1. Open a terminal and type “sudo apt-get install python-gtk2-3 libgtk2-3-dev”
  2. Type “sudo aptitude update” and “sudo aptitude install python-gtk2-3”
  3. Type “python -m SimpleHTTPServer” and hit return to start the server. You’ll need to add your domain name to the server’s configuration file ( ~/.config/simplehtpserver ): [domain] http://localhost:8000

The new Ubuntu 11.04 Natty Narwhal uses a Global Menu which puts the applications menus (File, Edit ,View…) on the top panel. In Firefox, this also removes the Firefox menu button in the upper left corner of the browser window. If you liked that menu button and would like to get it back then you are lucky because it can be done in just 2 easy steps!

First Step: Open the add-ons manager by going to “Tools > Add-ons” or you can press the shortcut keys “Ctrl + Shift + A”

Second Step: Locate the add-on “Global Menu Bar Integration”, disable it by clicking on “Disable” then click on the “Restart” buttons that will appear next.

Third Step: In the top most of the Firefox window itself,  click “Views > Toolbars” and uncheck the “Menu Bar” option.

TaDa!! The Firefox Menu button is back in it’s place.
