I've had Adsense code on the posts.aspx page for over 2 years with no problems but the ads have now disappeared when viewing site with Firefox or chrome. Works in IE (8). The code is inserted using a standard and supported process - a link to an anonymously accessible txt file added to a content editor web part. So there's nothing custom here. The code is getting output correctly and like I said works in IE8.
Since it's not working in more competent browsers and I've changed nothing, this seems to be something MSFT has caused. I know MSFT has been struggling with url management and I wonder if that has something to do with it.
I'd appreciate an answer (other than "clear your cache" which I've done by the way). Firefox and Chrome are now more widely used than IE, so not supporting them properly is not an option.
