I use McAfee Antivirus Plus. The Mozilla Firefox version I am currently using is 3.6.24, and it is not compatible with the McAfee Site Advisor. I would like to upgrade to version 4.0 Please send me the link so that I may download this.

Hi manthie717,

Is there any particular reason you want to install version 4.0? The latest version as of this posting is 9.0.1. There are a lot of benefits to running the latest version of Firefox. You can find information on updating Firefox in the Knowledge Base article Update Firefox to the latest release. You can also download Firefox directly at:

Hopefully this helps!
