Firefox tabs ?

I am trying to set up my Firefox tabs I want to open new window which do I uncheck or check or is it seperate from tabs which should be unchecked and check to open new window

boohbah I Uncheck the entry under Tabs reading "open new windows in a new tab instead." which others in the tabs options should be unchecked or checked

boohbah I have "open new windows in a new tab instead." unchecked which others in the tabs options should be unchecked or checked

Look at the screenshot he posted, that's the options selected by default. If you see it is checked.

I'm sorry i can't understand what you want exactly...do you want to have it checked so when you click on links it will open in a new tab instead of opening a new window, or...?
