A certain website doesn't work properly in Firefox anymore.

I used to use a website www.padmapper.com After a recent update to Firefox (I think 3 or 4 updates ago) I suddenly couldn't use the website properly anymore. It would load but some of the options of for instance choosing a price-range wasn't working. Instead of a display of numbers I got a display stating NaN. I tried accessing the website using Internet Explorer and the website appeared to be working fine using that browser. I am using the latest version of Firefox (36.0.4)

I checked the site out. Had no problem.

Make sure Java and Flash are enabled and up-to-date.
