Preventing before the unlocking of previewers of www

Hi all

I wanted to ask someone it know how I can to do it the app to prevent (on password of access) before the unlocking of previewers of www? Maybe is a some ready of app, someone knows?

Thanks in advance

All I can say is... huh?

:( it little.... and so completely seriously?

You want an application that blocks access to internet browsers before a password is given?

I will say otherwise, for every installed internet browsers I want to make the setting for all options only across password, its possible?

thanks
