I am usually using firefox for browsing.
now as i visited milovana a few seconds ago the page showed up ..different.
all the menues were ordered downwards
so for example "tease of the month" is an entry with 100% the width of the window.
the screenshot has vanished due to the host it was on it seems.
I use firefox for 99% of my browsing, the other 1% is using IE to test my website's compatibility (if everyone just switched to FF my job would be much easier :P)
But ive never experienced any issues with milovana.
i think i know the issue you mean though as ive had it on other sites. Instead of content being laid out correctly it just lists the content below each other.
I assume you reloaded the page? And it corrected itself?
If so i think its just a minor bug with either the way firefox loads CSS sheets for positioning or possibly an issue with flash components.
If all is back to normal now then theres nothing that really needs to be done about it. If you experience it more often just double check you are patched to the current version (i dont know it off the top of my head) and then disable all your addons and see if it makes any difference, if the problem soles itself when they are disabled, enable them one by one untill it happens again and thats the addon thats causing it.
If nothing seems to work you might need to re-install firefox
I sometimes use FF, but my comp is older and it eats up the system memory, so I don't do it all the time. It honestly looks like the page has timed out after loading the left column, try a cache reload, and if that doesn't work then try loading the site in Opera or Safari, IE if you must, to see what does and doesn't work.
