Reporter: 
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

btw: Thanks for the screenshot but please use an image format instead of a proprietary .doc in your next report.

Thanks for the reply. I need some research to do in order to fix this. 

Re your comment about the .doc. I do agree with you. On the other side it would be good if I could attach multiple files to a bug. This way I could have attached the two before and after screenshots in jpg format. But it was easier to just dump them in a word doc. Yes I know I could have used a picture tool and create an image blah blah but honestly, I don't had the time and users (that'll be me!) usually go the easy (lazy?) way. 

Cheers

PeterNZ: looks like your site is now fixed, is that right?

Sorry I don't know what gives you this impression. I got some help elsewhere in form of a RegEx string. Unfortunately that fixes Firefox 17 issues but raises Firefox <17 issues. So no, it is not fixed.

The change in Firefox gets reverted due to several pages that are doing stupid UserAgent sniffing.

Should be fixed with Firefox17.0.1
(help/about Firefox triggers n update)
