Some sub-menus on the main navigation bar are invisible in Firefox while all of them are visible in Chrome and IE.
"Sepetim" (Shopping Cart) page is visible in all three but other two sub-menus under "Hesabınız" (Your Account) are invisible in Firefox.
I have never liked Firefox.
This is my site with a child theme of Twenty Twelve: http://simayamama.com
Is there a way I can change my sub-menus to be visible (altogether!) in all browsers?
( The other problem, as you will see, is the width and the place of my Facebook plugin which I couldn't change through css but I'll open another topic for it. And one another problem which may make you vomit if you see is about mobilization -everything being lined up vertically without my permission- which I can't dare dealing with yet. )
