You may have ad / mal-ware. Further information can be found in the Troubleshoot Firefox issues caused by malware article.

Run most or all of the listed malware scanners. Each works differently. If one program misses something, another may pick it up.

Separate Issue: Update your Flash Player Note: Windows users should download the active_x for Internet Explorer. and the plugin for Plugin-based browsers (like Firefox).

Note: Windows 8 and Windows 10 have built-in flash players and Adobe will cause a conflict. Install the plugin only. Not the active_x.

I don't have any malware on my computer. This is the result of an add/link from facebook where they are trying to scam you. I saw one just like it for an android phone earlier today.

I just want to know how to Disable Authentication Required Popup for all web pages. How can I block a page from asking for a user name and password? I think it might be a proxy or sspi authentication request.

The webpage I linked has been taken down so I won't be able to try any solutions until another one comes along :(

Have you scanned your system?

Firefox is blocking that page for me, says it is a deceptive site. (Screen shot attached.) Do you have that feature disabled? See: How does built-in Phishing and Malware Protection work?

In a similar case, the only way to stop the prompt from reappearing over and over was to press the Esc key several times in quick succession. That stopped the page from reloading and regenerating the prompt so you could close out of it.

On your screenshot I see three pop-ups;   coming from your   OS.
You could post a question about this here:
answers.microsoft.com/en-US/windows/forum/windows_10
(for windows 7 as well)
This support forum is pretty similar to the one you're on now.

I suspect those are fake and should not be trusted. Windows security alerts do not direct you to a toll free phone number. Especially one identified as a scam when you search it.

Hence my suggestion to post this question on the   Microsoft forum.

jscher2000 is correct. The popups you see aren't from the OS they are fake images on the webpage.

Yes the webpage now comes up with the red screen warning it is an unsafe site.

Here is a link for a page that hasn't been blocked yet. I am sure it will be blocked soon. http://problemx305.ml/ff/

Your tip about hitting escape quickly worked. But I still want to be able to block this type of popup.

I will take a look at it and do research into the suggested programs. I never install anything without reviewing it first. But i am guessing there is no malware on my computer. I have Comodo internet security running. I ran Malwarebytes with nothing was found.

I   know   jscher2000   is correct;  again:   hence my suggestion to post this question   (about the fake popups)   on the   Microsoft   forum.
I think this concerns   Microsoft   as well, and it wouldn't hurt if they took some action.

Good for you   !!!

It’s very sad, but many of the software downloaders / installers will trick you into installing not only their program, but other programs as well. You have heard of the fine print in shady contracts, right? Well, some installers you need to look at the itsy bitsy teeny weeny fine print. You are thinking you are giving the installer permission to install the program you want by using the recommended option. But if you use the Manual Option Instead, you discover all kinds of stuff that you do not even know what it is or what it does. From now on, everyone needs to Use The Manual Option to put a stop to this.
