247183 - Transparency using the opacity CSS setting fails in Firefox; the -moz-opacity property renders either opaque or transparent

Status: RESOLVED DUPLICATE of bug 228441

(Firefox :: General, defect)

Description

[Ben]

User-Agent:       Mozilla/5.0 (Macintosh; U; PPC Mac OS X Mach-O; en-US; rv:1.6) Gecko/20040206 Firefox/0.8
Build Identifier: Mozilla/5.0 (Macintosh; U; PPC Mac OS X Mach-O; en-US; rv:1.6) Gecko/20040206 Firefox/0.8

The opacity CSS property does not seem to be supported. In pages which use the
-moz-opacity CSS property, Firefox renders any setting other than 1 as if it
were set to 0. That is, -moz-opacity is binary, as either visible or hidden.

Reproducible: Always
Steps to Reproduce:
1. Setup a simple page with a div; apply a style="opacity:0.5;"; the div will be
fully visible. Any adjustment of the opacity will not change this visibility.
2. Change the style to read style="-moz-opacity:0.5;"; the div will be invisible.
3. Change style="-moz-opacity:1.0"; the div will be visible.

Actual Results:  
Div displays as fully visible for all settings of opacity; div displays as fully
hidden for all values of -moz-opacity except 1, which is displays properly
(fully visible).

Expected Results:  
Ideally, the opacity standard will be adopted soon. Until then, the -moz-opacity
property should render as partially opaque; the density of the opaqueness should
be the decimal given, where 1=opaque and 0=transparent.
