FYI, my if statement was actually doing exactly what it was supposed
to. The bug was inside the body of the if (I didn't post that :-().
Long story short, I was confused. Basically prev and next are smarter
than I thought they were :-). For what it's worth, my updated code is
below. Basically what's going on is that I've got header rows and
detail rows. When I delete the detail row I check to see if it is the
last one for its header, and if so, delete the header. I may still
yet be doing it the hard way, but at least it works in Firefox now.
Thanks Karl and ricardobeat for your help.
if ($(theTr).prev("tr").is(".headerrow") &&
($(theTr).next("tr").is(".headerrow") || $(theTr).is("tr:last-
child")))
{
$(theTr).prev("tr").remove();
}
$(theTr).remove();
