The Test

1. Create a set up

• Put the install in a custom directory (C:\Betabreakers50 for purposes of this example)
• Do not allow Firefox to start when the installation completes
• Start Firefox with a new profile:
  • Change directory to the folder where you installed Firefox: cd C:\Betabreakers50
  • Run firefox.exe: firefox.exe -P -no-remote - This will bring up our profile selector window.
  • Use the "Create Profile" button to create a profile new profile
  • Once the profile is created, select it, and then click "Start Firefox"

2. Test

• ...NEED SOME TEST VIDEO SITES...
• Drag some of the above items from the tab bar onto the desktop to open them in their own window
• Drag these items back to the main window tab bar
• Try switching through some of these tabs in Full Screen mode
• Try restarting Firefox and restoring these tabs
• Try putting the system to sleep with Firefox running and resume the system to see if Firefox restores properly
