how do I stop the Firefox ad that wants me to download Firefox for Chrome?

You are running an outdated version of Firefox.

Please use Help > About Firefox to trigger an update. And then see if that problem is corrected, or not.

Do a scan for malware. It might be some kind of hijack attempt.

I do not have Chrome on my laptop, which has Windows Vista. Yet, I continue to get a Firefox ad telling me that Chrome is not protected. How do I stop the firefox Chrome ad?

Is this on a Google.com site as Google tends to have a mention to get people to use the Google Chrome web browser on a corner.

The Firefox web browser and Google Chrome web browser are completely separate web browsers.

Maybe give a link or url where you see this or add a screenshot to your reply on what you see?

Can you attach a screenshot?
