How to undo recent Firefox upgrade? McAfee Anti-Virus Plus Virus Protection no longer compatible.

A newer version of Firefox has been upgraded on my laptop. After the upgrade, a message came up that my McAfee Anti-virus Plus would no longer be compatible with the newer version of your product.

I still have several more months use of this virus protection and do not have the money to buy something else. I need the virus protection to work, and need detailed instructions as to how to go back to the older version 4 of Firefox.

If you can not help me, I will have to go to IE and I really don't want to do that.

I have a fairly new laptop purchased in Oct. 2010 and am running Windows 7 operating system.

Thank you.

ANSWER! Go to your downloads folder and find your old Firefox 4 setup icon. CLICK IT and reinstall it! It will override your recent upgrade and return you to Firefox 4! WOOT WOOT!

Mary Anne, you'd better ask this question on the McAfee forums as well. Go to https://community.mcafee.com/community/home and register for a user account, then post the question. You're the second person I've seen who says they have this problem, and I don't think a new version of Firefox should suddenly be incompatible with your antivirus protection.

Mary Anne, Only the SiteAdvisor extension is incompatible and that is being worked on, estimated solution mid-July. By the way, it isn't just McAfee's browser extension, Norton's Safe Web and I believe others are also similarly affected. The only browser safety extension not affected is WOT because it works differently.

All I see are people saying, "wait till it's corrected". I have a different issue where my other programs are not compatible with 5. I need to go back to 4, I use those programs often. HOW DO I GO BACK? That was the question. Can I or can I NOT return to 4?

Thank you much loveualatte. Your answer actually made the most sense. Other replies were telling me to do things I had already tried with no success.

One solution was worded in such a way that it made little sense to me. The instructions for undoing the update were much like reading pig latin. I was never much good at speaking that language.

If I have any more problems, I think I will just ask you first if that is ok.

I am still learning.

A good laugh for you. The first time in '97 that I got my first computer, the second thing I did after I turned on the computer, was to somehow delete the operating system.

College courses were no help, so I decided to start the school of trial and error. that has been and still is the best teacher.

Have a great evening.

Thank You so much loveualatte! I have been so agitated since the (upgrade?) more appropriately named DOWNGRADE. I tried what you said but Fire Fox 4 was no where to be found any where in my computer, but I did go to the site and re-download it. Again Thanks
