Where can I find a good free password protected App/service which prevents access to any adult material through the browsers?
I need to block all adult sites and adult content from Firefox, Chrome and Safari?

Mac OS has built in parental controls that work with those browsers (FF, Safari, Chrome,...). They can be activated in system preferences.
Blocking any adult material is simply impossible since it is impossible to automatically classify or recognize it. There are services with blacklists which can be just a small approximation or software that tries to analyze the content but these are prone to errors.
You will soon notice how incomplete the lists are or how many false positives you get from automatic software.
The first time you will try to contact something like "Bus Express" and the software will tell you that the domain "busexpress" is blocked (has "sex" in it) you will see how poorly they work.
Edit As suggested in the comments by white listing only safe site you could be able to achieve what you want. Maintaing a list is on the other hand almost impossible unless you limit the white listed sites to small manageable size. Keep in mind that any site that could present you the content of a second site (e.g., Google) is potentially unsafe (for example the cached pages on Google)
If you sign up for an account, OpenDNS uses a free service that will block adult content. You just have to set your DNS server to their DNS server.
