Firefox crashes

I was using Wetransfer.com to upload a 500mb zip file from a macbook pro (brand new) and it crashed after many attemps (most often near 97%) but a few times around 40%. It would freeze and finder would ask to resume but not work. I used Safari and it worked right off the bat, right away. How do I use mozilla in the future if it can't upload files to wetransfer.com
