Hi vishak,
Nice post from you, Google chrome browser has the incognito window to have secure browsing , whereas in Mozilla Firefox browser have private browsing option and other security options are provided for secure browsing. For protection against hacking and phishing one must use good antivirus and anti spyware program. When good antivirus or anti spyware is used then we can have secure browsing. As bharath said we can lock pages using https:// option but cant protect against ip phishing hence we have to use a good anti virus or anti spyware program for secure browsing.
