Recently i have bought a new computer and i tried to install Firefox on my system. But after downloading the .exe file from the internet i cannot run it on my system. When i click on the .exe file, the installation process run very fast as it is installing anything. I don't know why this happen whenever i try to install Firefox on my system. Can any one help me to install Firefox on my system? Would be graceful to you if any one help me out to resolve this issue.
