>After adding NoScript plugin to my FF, and whitelisting whole UT on it, I got pretty much everything working as it should... except search.

This is quite exceptionnal. I do not have any CGI link into the site since last night. And, that one, it was converted three days ago. Can you login again, click on Search, and send me the view source of the search page (the one with all the seach criterias). I will verify first to see if you are having the proper page. Also, before doing this, can you clear all the temporary files and restart the browser?
