Remember when Firefox was the first browser to have "tabbed browsing"?

Obviously UBO isn't a first party feature - but if only Firefox could generate as much traction about ad blocking as they did with tabs.

I'm fairly sure Opera introduced it first.

		Yes, well, kind of. Opera had Multiple Document Interface (MDI) which was actually (back then) far more flexible than tabs. But yes, Opera was first with MDI, and also I suppose the first web browser for the smartphone.

		Yes. Opera (original, not what is called Opera now) introduced tabs first. I believe in the 5.0 version with presto engine.

Yeah, I remember.

I also remember it automatically blocking popup ads. That was a huge deal.
