Firefox allows you to use coding to manipulate the opacity of an image.
"Opacity" refers to transparency; the lesser the opacity of an image, the more transparent it is.

Opacity:1.0 shows you all of the image; Without any filters applied the opacity of an image is 1.0 (fully opaque).

We use CSS to define the initial degree of opacity in Firefox:

<IMG style="-moz-opacity:0.5" src="test.gif">

Valid range of values for -moz.opacity is from 0 to 1, where lesser equates to more transparency.

<IMG style="-moz-opacity:0.6" src="alta.gif" onMouseover="this.style.MozOpacity=1" onMouseout="this.style.MozOpacity=0.6">

-For CSS opacity to work in the browser it must have some placement specified. Mozilla recommends that we use float:left; and position:relative; to work in Mozilla Firefox. The opacity code for simply displaying an image is more straightforward.
-<pre>
-<span style="float:left;filter:alpha(opacity=25);-moz-opacity:.25;opacity:.25;"><img src="v90.gif" width="50" height="50"></span>
-</pre>
