This is another reason why I don't like Firefox screenshot. It doesn't allow for a full browser screenshot to show the site the user is on. End of rant... ;-)) Please provide the site.

Hi canadaandchile, Are you saying that this only happens in Firefox?

Yes. It does not in Safari.

It took awhile to remove the scam pop up. Some company helped me.

I hope they didn't charge you. It's a common practice of scammers to present a fake alert, then charge you for getting rid of it. Here are a couple of articles that should help:

• Avoid and report Mozilla tech support scams
• Troubleshoot Firefox issues caused by malware
