Going to request tab in 8.2.0 Build 8210 using firefox results in server error page

Hi,

We have recently updated to 8.2.0 Build 8210 but now when I open the request tab (/WOListView.do)  in Firefox (23.0.1 Windows 32 bit on Windows 7) it gives me the infamous "
HTTP Status 500" this is not happening when it is opened from Chrome or IE

Is anyone else having this happen?

Neil
