I understand that "_blank" opens a new window in IE or Firefox.

What's the equivalent command to open a new tab in Firefox?

Thanks

There isn't one, at least none of which I'm aware. That's purely a user setting - one that can only be determined by each individual visitor. The same thing goes for Opera in reverse. Opera, by default, opens a new tab for new windows (which makes a lot more sense than Firefox's default setting). You can change this on your own, but site authors cannot make this decision for you.

I belive saw a W3C draft taht implied _tab would work in XHTML 2.0...Don't know if any browsers have implemented it or not.

I doubt the W3C would endorse such functionality. All of the documentation from them that I've read stipulates that this should be a user-controlled feature. If they want a new tab, they can open it. Ditto for new windows.
