What is Firefox Setup 3.6.10(2).exe and is it necessary?


What is the function of Firefox Setup 3.6.10(2).exe and is it necessary?

When I logged into Windows Live Hotmail today, I received a message to upgrade my Firefox browser by installing this programme. I am unable to find out any information about it on the Mozilla website.

I have downloaded to file, but am hesitant about installing it until I know more about it.

That probably means you downloaded the setup file twice. The setup file is called Firefox Setup 3.6.10.exe, but if this file already exists, a second one called Firefox Setup 3.6.10(2).exe will be created.

Your above posted system details show outdated plugin(s) with known security and stability risks.

Update the Java plugin to the latest version.
