Margins not working properly on Firefox

[Otaku Ichise]

Somehow the top margin of one <div> moved itself thanks to one tag <ul> inside of it,
it could eitheir be another <div> and still same would hapen.

Any sugestion on how i should could beter on Firefox instead of my way of coding?
Any error or bad way im coding let me know please.

Hmm, that's a lot of <div>s. You could begin by simplifying the markup. There are a few nested divs that you really don't need.

It all looks fine here? Can you better explain your issue?
