Sounds like a simple explanation, and Firefox indeed shows an error 
message about openUp being undefined.

Well, this wasn't really my code, or even my code. :-) Just an 
interesting observation. And although the fix would be simple, it seems 
to be legacy code that nobody wants to take care of.

Indeed, if someone wants to open a web page in a new window with 
specific properties, it is surely much better to set up a normal link, 
then add an onclick handler that creates a window for the link to use, 
so that the page works fine when JavaScript is off and in a 
cross-browser way when it is on. But I'm afraid there's a lot of code 
around that uses javascript: URLs in href attributes instead of any 
robust approach.
