I have internet options selected for quick tabs and tab groups in settings, IE8 WIndows XP. I can open a list of favorites from the menu using the blue arrow as a tab group. I can then use the quick tabs button to show the groups open. However, I do not have the "add tab group to favorites" option in the pull down menu for favorites at the Favorite Bar. Is this a Vista feature only? I just checked two of my Vista basic machines SP2, one also does NOT have the option. The laptop DOES have the option.
