I can't deactivate my facebook account. Help?

[Dee]

I keep getting an error message every time I type in my password to deactivate my facebook.

People say this works:

1-press account in the menu
2-press application settings
3-choose authorized from right drop down
4-in developer press profile
5-then press in left "go to application"
6-in the right side you will find my applications
7-navigate there and delete if you have any then deactivate


I can't find (in step 4) the developer thing. I want to deactivate my facebook. Can anyone here help me?
