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?
