If you want to change the default browser in Flex, you can do this in Flex Builder by going to Window -> Preferences. Then expand General and choose Web browser. In the ‘External Web browsers’ list choose the browser you prefer – in my case Firefox.
This is it. Enjoy!
The default blue background color in Flex 3, set while the application is loading, is pretty annoying in my opinion. You can change it easily by setting the default background color property in Flex Builder. You can do this by selecting the project, then right click and choose Properties. Go to Flex Compiler and then in the ‘Additional compiler arguments’ type this:
-default-background-color #ffffff
This will change the color of the application while it is loading to white.
