I'm suddenly getting repeated/multiple Mozilla Firefox "Browser Alerts", "System Warnings," and "McAfee Critical Virus Alerts" that are wrong and dysfunctional. They pop up every few seconds. They contain "Remove virus now" and "quick scan" buttons, but these only take me to a bright red screen that says:

"Deceptive site ahead Firefox blocked this page because it may trick you into doing something dangerous like installing software or revealing personal information like passwords or credit cards."

These come even though I haven't tried to access any "deceptive sites." I have to x all of them out to clear my screen.

There's obviously a defect in your warning system. How do I stop this?

I'd never seen a Windows Security prompt when attempting to view saved passwords before, so I was confused when I saw it for the first time recently. I have a primary password set within Firefox, and I never enabled "Require device sign in to manage passwords" in settings. I also cannot disable this setting without entering my Windows password.

I was alarmed that this may be a malware symptom, as I'd recently connected to a new public wifi network. Is it a known issue for this setting to become enabled by itself? At the time of this issue, I was running 150.0.3. I have since updated to 152.

When I logged on to my laptop this morning, it appeared that my Firefox was updated. I immediately was inundated with pop up alerts from McAfee. I checked it and learned it was a scam. However, my husband thought it was legit and allowed them to do a scan!!!! He didn’t download any software. What do we need to do?

(I did see the solution to stop these pop ups and have already resolved that issue. I’m just worried that some party scanned my laptop.

How can I suppress a recurring pop-up in Firefox that claims my computer is infected with a virus and it instructs me to download McAfee Antivirus to clear it out. I've done multiple scans with my Norton Antivirus which showed I had no viruses. The fake pop-ups appear to be coming from Firefox.

I am unable to log into my energy provider, when I log into my bank I can't use some features like seeing all my transactions, I can't log into Twitter, I can't play anything from Substack.
