'browser.tabs.opentabfor.xyz' Settings

What *exactly* is the purpose of the prefs.js-settings 
'browser.tabs.opentabfor.xyz' and how are they supposed to work?

Are there any other prerequisites or don't they work with Warpzilla, but only 
with the Doze version?

I added 'browser.tabs.opentabfor.bookmarks' and 
'browser.tabs.opentabfor.windowopen', but still a new browser window is 
popping up, when I click on f.e. http://gknot.doom9.org/ from within 
http://www.doom9.org/ or (Ctrl-)clicking on a bomark still overwrites the 
contents of the currently active tab.

So what is wrong here:
my expectations, some (missing or prohibitive) settings or something with the 
OS/2 version?

Why do still links popping-up in new windows, when I use the above statements 
in prefs.js rather than in new tabs?
Or is it some kind of regression with the 1.2b releases?
