Can't play Flash in Firefox: Problem with rtmp:// .flv stream (Problem with Adblock)

[Elice]

This is for this video:

First of all, I looove Replay Media Catcher and nothing else comes close to what it can do. But I'm having a problem and it has more to with Firefox so hopefully I can sneak my question in here.

I can't play this video in Firefox but I can play it in Internet Explorer. I tried using Orbit Downloader and Grab++ but this happened.
Nothing.

I hate Orbit Downloader, it made IE horribly slow and I want to get it off my computer as soon as I can. I would really, REALLY prefer to use Firefox/RMC but I can't if I can't play the video in Firefox. By the way, why can't you download from a link with RMC? Is it different for RTMP versus HTTP?

I don't understand why I can't play this flash video from dolceandgabbana.com if I can play the followin flash video from chanel.com

Someone heeelp me.
