Hi, please help me. I use Firefox for browsing and I get trouble to open webpages on www.mobile.de website. I get following error message: "Firefox cannot open this page For your security, suchen.mobile.de does not allow Firefox to display the page if it has been embedded by another page. To view this page, you must open it in a new window. More information… Reporting such errors helps Mozilla identify and block malicious sites" There is no problem to view the webpage with other browsers but I need Firefox because I use an extension....
