White space on top of the page in FF

Question

I'm getting a big whitespace on top of my page after login only in firefox. I tried to inspect all elements and can't find anything wrong with it. I also checked for uncollapsing margin but can't find any.when I scroll down and then up space will be removed from the top but when I refresh the page space will come.
