JA University (Joomlart) Mega Menu dropdowns don't work in EasyBlog on Firefox

Hi,

EasyBlog was installed on our Joomla 2.5.11 which uses Joomlart JA University template. This template uses the Mega Menu dropdown menus off the main menu bar.

When we go to our EasyBlog page in Firefox (testing with latest v. 22), the JA dropdown menus don't work...just as if JavaScript had been turned off.

I tested on IE8-10, Safari, Chrome and Opera 12&15 and do not experience the same problem.
I tested on WinXP and Win7 and always have same result.
This is only a problem on the EasyBlog pages when using Firefox and the JA template. I tested after complete clearing of all caches. The issue was confirmed by a remote collaborator.

Any ideas or tests I should try, or fixes? Our EasyBlog entry point is here...

Thanks!
