META not working in Firefox

[neeraj23]

The following works fine in I.E. but not in Firefox (though it doesn't affect page rendering or function).

Is this just a support issue with Firefox verses IE.? I assume so....

<META HTTP-EQUIV="Page-Enter" CONTENT="blendTrans(Duration=1.0)">
<META HTTP-EQUIV="Page-Exit" CONTENT="blendTrans(Duration=1.0)">

Thanks in advance,
