Hi, I’ve been using Firefox as my default browser for some time now. And lately I’ve been noticing a style tag added in each and all randomly visited URL. This style tag contains loads of links, mostly ad references, and seems JavaScript based, as shown in attachment. I don’t have extensions anywhere and I ran defender, some malaware software and antivirus but there was nothing to report. I’m intrigued and trying to find out from where is coming from and how the style tag gets attached inside the body of the HTML page automatically and randomly to any visited URL. This happens with all mainstream browsers. I mean … what the hack?
