Implementing Firefox profile in Selenium Webdriver with Java

While automating a web application, we want the application to be opened in a customized browser. A browser without any theme/extension/addons or with customized settings; settings like pop-ups are allowed, certain sites are certified etc. The reason why we want a different browser profile is our regular use browser has several addons installed, several bookmarks, and some browser level restrictions which might hamper the proper functioning of the AUT.
