WOOHOO found a workaround to the madness..
I started searching for this issue and ran across this bug report..
One of the replies to the bug listed a 'firefox feature' that can prevent this from happening.

It appears to be a Firefox feature.
Can you try to
1. bring up about:config
2. set browser.tabs.loadDivertedInBackground to True
I made this change and now iceweasel appears to be firmly planted in the workspace I put it in.
It looks like the root cause is actually a gnome metacity bug..
Either way I'm happy at this point..

I just looked at the thread you linked to and the same workaround is in there.. I must have missed it somehow.. Man I could have had this fixed a couple days ago.. :/
