white firefox blocks

I am going crazy by the time anyone read this :p
the problem is simple, I have the following functions:

[CODE]function showf(objId)
{
document.getElementById(objId).style.display = "";
}
function hidef(objId)
{
document.getElementById(objId).style.display = "none";
} [/CODE]

(there's a table row I want to be appeared/ disappeared on a click)

in IE, everything goes fine.


Firefox hoever; gives me white blocks on the display:none
