I just noticed on my website that the sIFR-ized headers don't work in Firefox 3. It works in IE7, and I presume it works in other browsers though I haven't checked yet.
It used to work in Firefox 2, and I haven't changed anything that affects sIFR so I'm not sure what is up.
I did a bit of debugging and basically this returns false in Firefox 3, when it should be true:
I'm not sure why it is false in Firefox 3 but true in IE7.
typeof sIFR == "function"
Can anyone shed any light on this?

Another sIFR related issue (or maybe IE issue) is that I can't get the width of the header to change in IE, though it changes in Firefox.
