Answer 2

Go to Window -> Preferences -> General -> Web Browser. There you can see the available browsers listed and a radio button for selecting either the internal or external browser. Do check these settings and try to launch again. It may be that the path you have shown, where "firefox.exe" resides has not been updated within the Flash Builder.

Answer 3

Rigth click on the flashbuilder shortcut -> run as administrator

Answer 4

If you can't run as an admin, try checking on the security settings to ensure all users have full access to the Firefox directory & files. This almost has to be security related, unless Firefox is actually a location different from where it's looking.
