I found a way to get the opacity to work with Mozilla type browsers, hope you would implament this in your CSS for use users with Mozilla and use the x79 style.
/*cat title alpha*/
table.alphame {filter:alpha(opacity=75);-moz-opacity: 0.75;}
span.alphame table.tborder {filter:alpha(opacity:75);}
/*alpha trickery--since the preceeding 'body' makes these more specific, they override the standard attributes, even if they get defined after these*/
body td.fdblues {background:transparent;}
body td.fdflcc {filter:alpha(opacity:50,style=3,finishopacity=100);-moz-opacity: 0.50;}
body td.fdthtext,body td.fdthpic {filter:alpha(opacity=75);-moz-opacity: 0.75;}
body td.pbc {background:transparent;}
body td.pbcbe {filter:alpha(opacity:75);-moz-opacity: 0.75;}
/*make sure that any possible second levels stay at full (relative) opacity*/
.tborder .tborder,.alphame .tborder {filter:alpha(opacity=100);}
.headernav .vbmenu_control {filter:glow(color=#001020,strength=2);}
body td.fdflcc {filter:alpha(opacity:50,style=3,finishopacity=100 );-moz-opacity: 0.50;}
This illustrates that you do not actually understand the effects that you are trying to replace. FF apparently does not support opacity to the same degree that IE does, judging from the link you provided. If you really think that your suggestions are so great, why don't you put them in your master style sheet with an !important flag? Most of the class names should be unique enough that it won't be an issue.
Well he seemed to misunderstand me. I never meant for my suggestions to be 'so great'. That part sounded like pure sarcasism to me. I just happen to come across a way to use opacity in FF. After testing, I see it does the same affect that alpha does with IE.
I just don't know what he meant by:

FF should allow you to specify a custom stylesheet which is applied before any other rules. You can put your modified CSS there. The !important flag can be used to override a webpage's stylesheet (as attributes marked !important override those not so marked), but since I don't specify a -moz-opacity attribute, it's actually not needed here.
