Firefox 3 onwards has a nice feature which warns you of sites which are suspected of forgery or attacks (through trojans, malware etc.). Unfortunately the feature is too intrusive and warns you repeatedly, nags you to death is a better phrase to describe it, even when you have confirmed that the site is genuine. If the site requires some kind of authentication, then you are toast. While accessing a media site, I faced this problem. It required me to login. The phishing database used by Firefox mistakenly identified it as a probelmatic site would not in any way allow me to login to access it, going into an infinite loop. The long and short of the story is that I had to ultimately use Opera to view the site. Today I was thinking that there must be a way for us to disable the pesky, and rarely useful, warning messages from Firefox and after a minute of looking throught the options I found it. You too can do it in 2 simple steps which will take you less than a minute.

The following guide will focus on Java
