You could use the contains template function... contains($xf.request.getUserAgent(), 'firefox')

I'm not joking, I was searching for HOURS trying to figure out how I could modify a template based on something, anything, I could put in the link on the referring page. This was just enough of a hint to make me look at Request.php (I don't know PHP) and see that I could use $xf.request.getRequestUri() along with your code to change the template based on a URL variable. I'm sure there's a better or more 'right' way to do it, but this seems to be working, so THANK YOU
