Locking down Firefox

In IE, one goes to:

Tools/Internet Options
Security tab
Select Internet icon
Click on Default Level
Move slider to High
Click Apply
Click OK

Then, one adds trusted websites to a white list.

Can one remove access to _any_ website initially in Firefox?
If this is not possible, can this be done in another non-IE browser?
