Did Opera really bring us tabs first?

I remember using NetCaptor (an IE shell browser) long before Opera had tabs.

Maybe Opera popularized it first?

I encountered them on a 'Nix browser, Skipstone (gtk toolkit browser, probably using Gecko) back in 2000. What I heard was that Opera had pioneered the feature. At the time, browsers were one window per page, which ... pretty much completely sucked.
