In my case many sites relying inf javascript or dhtml show without format in a plain blank webpage with only the text, pictures, etc out of place.
Reload the page dont work, ou had to do a fully reload clear all or press 
[shift] + [F5].

The extension are the same than Fx 16.0.2, in firefox safe mode happen the same

Bug 588909 - Replace Gecko/<date> with Gecko/<version> in UA string

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

Yuri: the file "stmenu.js" on your site, which says at the top:
/*DHTMLMenu, (c) 2006, SourceTec Software Co.,LTD  -  www.sothink.com*/
is doing bad user agent sniffing, which has broken because of a change we made in Firefox 17.

The code has been compressed so it might be a bit tricky (although possible) to fix by editing it directly. Perhaps you could ask SourceTec Software for an updated version?

I edited the version comparison line in the stcode.js file & it seemed to have sorted the issue.

Changed _r.bIsFX&&_r.oNav.version<=20021130 to _r.bIsFX&&_r.oNav.version>=16;

We reverted the change in the Useragent string in Firefox17.0.1 and this should remain.
