Opera was so fully packed with features. I started from Opera 2 or 3 from what I recall and stayed until they became Chrome. No other browser came close in features while being fast.

They had lots of cool featues built in:

IRC Client

Email Client

RSS Reader

Note taking (I used it a lot)

Gestures (those were awesome, I fondly remember holding left then right click and the other way around to move back and forward, but these proved to be a sign of Operas decline, some bugs with them were never fixed while we kept getting newe releases, (remember the potato ad?))

Sharing local files as a website right from your browser

They invented tabs

They might have had torrent support too, don't remember clearly.

It was fast even with all this.

Vivaldi's UI is built in JS, it feels slow, all my clicks are slow. I never got myself to using it more than a few minutes.
