Pop up message of xd_proxy.css, facebook issue!
Last week, a large amount of customers complained they were getting the following pop up message almost in every single website using IE:
xd_proxy[1].css
Then a notepad opens up with the following information:
.app_content_51546247891 a.uiLinkSubtle { display: none; }
.app_content_51546247891 a.UIImageBlock_ICON_Image { display: none; }
#bootloader_Zvucx { height: 42px; }
After further investigation, it was proved to be a facebook script issue. This error was also ovbsered in Firefox, Safari and Chrome, not just IE.

It seems to affect every single website that uses social plugins for Facebook.
