===Installer/Updater Use Cases===

** There is no access to the channel switcher from the nightly build.

* 2. A user downloads the Aurora build from the [http://www.mozilla.com/en-US/firefox/channel/ download] page

* 4. A user downloads the Release build from the [http://www.mozilla.com/en-US/firefox/channel/ download] page.

** If the Release build is put in the same directory as the 5.0b1 Beta build, it replaces it since the app name is the same.

** If I put the Release build in a different directory, I can have multiple versions of firefox.app.
