Diễn đàn hỗ trợ Firefox

Using the latest Firefox update with Windows 10. I've got three popups in the lower right corner of my screen (see uploaded image), and each refreshes periodically with a musical phrase that sounds like a smartphone notification. Though each says "Mozilla Firefox" in the upper left hand corner, the popups are present whether the browser is open or not. All three say, "via da75iiinaffc73ar8f20.yird-protect.pro".

I've already gone to Settings, cleared my History, made the recommended changes in Permissions and Data, and closed and reopened the browser. The popups remain.

I am getting popups constantly from Mozilla Firefox. It is using a sign on as d9nnarOhubcc73e1106g.alphatechboost.co.in

How do I stop these?

I'm using an out of date Windows 10 laptop. I am aware of the Windows 10/11 thing. I know. I've got my own reasons for not updating this one, it's not my only device. I get it. I understand. I know. My settings are how they are on purpose. I do not need to be nagged in this fashion.

How do I turn this off? I can't find it in settings. It's not appearing on any of my other browsers. It's just Firefox. Please help, it's driving me crazy.

Thanks in advance.

I am receiving pop-up messages indicating CRITICAL ERROR! and "Click here to remove them!" followed by a URL ending with velonexa.com They appear as though they are from Mozilla, but we know better. I try to close the window and, of course, without clicking the url or the Dismiss button, but they keep reappearing. There are three stacked windows, constantly appearing as the pop-up windows are closed. Any thoughts or recommendations to eliminate? I've tried shutting down and rebooting. Pretty confident these are not from you. They are also always on top. I try to do a screen capture or print screen and i only capture what is behind them.

I know this is not generated by Mozilla, but thought you should at least be aware of them.

Very often while navigating around the website of a tool I use, I get an intrusive pop-up in the lower right corner. A screen shot is attached.

I first approached the website owner, but they explained it's a browser issue, no a website issue. They did, though, suggest that clearing cookies and cached might help ... But it didn't.

Is there any way to suppress that?
