This is a very short post, but it’s worth putting up because it shows how browser features go from a vendor-specific implementation to a fully supported standard.
In Firefox 3.5 we no longer support the Mozilla-specific CSS property -moz-opacity. Developers wanting to set the opacity of an element should use the standard opacity property instead.
We introduced the opacity property way back in Firefox 0.9 and -moz-opacity was deprecated. And with Firefox 3.5 we’ve finally removed it.
A long road for a simple property, but it’s worth mentioning so people understand the time scale for these kinds of features and how they relate to standards.
Anyone else seeing a strange rendering glitch on this blog where the “content” div, which has a white background, has zero height? It makes things very hard to read (grey on grey)…

@Gerv – working fine here?
I wish CSS had a way to specify that a container should be exempt from the opacity of its parent, or that a container’s opacity shouldn’t apply to its children…
Chris: seems to have fixed itself.

Keen, that’s how -moz-opacity worked before Firefox 0.9 when the implementation was changed to conform to the standard (which is more logical but also less flexible). You can get a similar effect by using rgba() colors however.
border-radius, box-shadow and text-shadow should be next in line,
Thanks for this info! After upgrading to FF 3.5, I was unable to view floor plans in my Cisco WCS (wireless control system). Turns out this is how they overlay the WCS heat maps on top of the floor plans. After my browser upgrade, all I saw was the heat map with no location info. A few simple substitutions in the wcs.css file and it now works properly again!
I would love to know what that WCS fix is Tiger Ivic, I’m having the same problem and am not much of a web designer
I also would love to know the WCS replacements you made.
Thanks
@adam & Ed: as stated on this post, beeing it’s main purpose, he replacce the old “-moz-opacity” -deprecated & now removed- to “opacity” in the CSS file.
