Hello people, I have a desktop computer which is installed with Windows XP. The computer has an Internet connection to it and Mozilla firefox is installed as the default browser. I downloaded the BetterSecurity add-on for Mozilla firefox for protecting my Internet surfing sessions but whenever I try to install the add-on, the browser gives the message saying "Unable to install". I cannot understand what is the reason behind the problem and hence want to know Why cant I install BetterPrivacy addon on Mozilla firefox? Any suggestion/solution about the topic are more than welcome.
