While there has been no "official" bug report, some community members elsewhere have posted minor problems with Firefox rendering of the Netquery 3.3+ user interface.

It appears that Firefox is not handling the float:right style properly for images within fieldset legends. I guess I must have added that after my last Firefox check thinking that, since it passed W3C validation and worked in MSIE, Firefox would have no problem with it. Obviously, I was wrong about that. It's a good browser, but none of them are perfect.

Anyhow, the simple "quickfix" solution is to edit the Netquery CSS stylesheet that you are using (or all of them) to remove or comment out that float:right style found there as:

input.floatbutton, img.floatbutton
{
vertical-align: middle;
float: right
}

Just take out the float:right and not the vertical-align:middle style. Unfortunately, doing that puts those buttons at the "wrong" end of the fieldset legends in my opinion, but I guess it's a small price for compatibility. I'll try to come up with a more elegant solution for Netquery's next upgrade release, but it doesn't look promissing. Firefox doesn't even seem to honour text-align:right within fieldset legends.
