Mountain Lion and Zipform - Zip Forms -

Being an Apple fan and Hosuton Realtor, I was delighted to wake up yesterday and download Mountain Lion on my macbook pro - until I realized that my Zipform Online would not work. I called Zipform technical support and they walked me through a couple of settings. On the picture in this post, we went under the "network tab" and then selected "delete files". This seemed to fix the problem in Safari but my Firefox is crashing when trying to load Zipform. I am not sure if it is something wrong with my computer or the Mountain Lion upgrade.
