Open In New Tab doesn't work

I use Firefox and Safari and I'd like to be able to open subforums in a new tab. For instance, I like to open up all the subforums I am going to read in seperate tabs, then go through and read all the subforums in one pass.

however, if I open a subforum in a new tab in Firefox, all I get is the Splash page for the forum telling me what the subforum is about, I don't get a new page with the frame for scrolling through threads in the subforum AND the splash page.

this is with a Pro account on Firefox 3 Beta 5/Mac OS X, but AFAIK the behavior is the same in other conditions.



 please fix this.
