the mystery of the vanishing web form

http://poland.inbulgaria.org/search

This web form, based on jQuer开发者_运维技巧y, but also including a SVG map control made with Raphael, appears correctly in Opera 11.51, as well as IE 8, but, for some reason, doesn't render at all in Firefox 6. Any clue why?

First thing I noticed is that you aren't escaping some of your class names and ID's with quotation marks, eg

<div class=advBox id=advOfferType>

Firebug is giving NaN values for the positioning of these elements which is a bad sign. Escape those IDs & class names, then get back to us.

Frustrated, I asked this question in a "share your mood" thread on some tiny forum with literally 5 users, and... I got a solution.

Adblock is blocking the form.

Yeah, silly as that. (:

Maybe it's because it's called Advanced Search, and there are a lot of DIVs with classes starting with adv.

Now that's something I've never heard happen to anyone else...
