Firefox 17 breaks my DNN Online shopping site and they are fully aware of this - thanks Mozilla. Reply to my bug:
"Your page is doing Useragent sniffing and it fails because our Useragent string format changed.
an example for the old User agent string
Mozilla/5.0 (Windows NT 6.1; WOW64; rv:10.0.8) Gecko/20100101 Firefox/10.0.8 and the new one:
Mozilla/5.0 (Windows NT 6.1; WOW64; rv:17.0) Gecko/17.0 Firefox/17.0"

Can anyone tell me how I can fix this? Or point me to some information? Google didn't really come up with anything useful.
