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?

How do I stop pup ups with several different warnings. At the top of ALL popups say Mozilla Firefox . I clicked DISMISS, then another one will pop up. 1.) Red shield with the word Warning! Click here to secure device! anti virus notification. 2.) Red and black shield say Virus found. 3.) Blue Windows symbol with a the yellow triangle and !, Click here to remove it 4.) red setting wheel, Trojan virus detected, Scan and delete your system.

Please help

Windows Defender is blocking Yandex.Ru, which is not even been tried to be access from. It showed in the Event Viewer that firefox.exe tried to reach Yandex.ru. Why is Firefox trying to reach there? There are no extensions apart from Firefox Multi-Account Containers installed.

Please advice.

This happens occasionally for many months. It is still happening on v147.0.1. I start the computer, open Firefox, and the browser loads previously viewed pages, including my Gmail account. The Gmail page has me already logged in, and I DID NOT provide my password! This has to be a big security risk. If some one were to use my computer, or it was stolen, they would have complete access to my Gmail and all Google properties! OS - Debian GNU/Linux 12 (bookworm) Kernel v6.1.0-42-amd64 Firefox v147.0.1 (and MANY previous versions)

Since several days every time I visit a webpage I see that there is a popunder from syscsrv.com!

What can I do to stop this?

Have tried different solutions like Malware product and cleaning cashe and cookies. When I search a known safe site I get redirect by Convertitmas stating the (known safe) site is unsafe. Best regards Henrik Nygaard

I have several pop up ads stating viruses and trojan horses have been found. These are all trojan horses that they want to infect my system with. They are coming from Mozilla Firefox and I have no idea how to delete the pop up ads from my screen and computer. I do know they are false as I have McAfee and Malwarebytes and they both show that I do not have any viruses. I know if I ask them to fix this they will infect my computer. I need to know how to delete them thanks
