Opera had no real tabs at that time. It was still MDI with a button-bar for fast access. Was'nt the browser doing this at the time, and it was'nt as good as Mozillas Tab-addon, which later was built into first firefox-versions. Opera added true tabs some versions later, while still hanging someway on the MDI-tradition.
