Vivaldi's predecessor, Opera, actually included an IRC client that I used back in the day. I maintained an interest in Vivaldi because Opera Mail was easily the best client I've ever used, and while Vivaldi Mail lacks a few of the features that I appreciated about Opera (e.g., select-to-quote, default top-quoting/bottom-response, obvious text-based emails), it's still far and away the best current desktop application.

Opera used to have a torrent client.

And an HTTP server.

Except that Mozilla wrote their own engine.

I miss Presto :(

Very fast on super slow embedded devices.

History is a closed loop. Maybe they can build their own browser engine!

"Maybe they can build their own browser again", but the web is not the cute little thing it was back when everyone was writing their own engines. Even a small team literally cannot write a web engine with enough support for the majority of common use cases anymore. It's literally why Vivaldi went with an off the shelf engine and focused on the browser part instead.

I was thinking the exact same thing. Mozilla also had a WYSIWYG webpage editor for some reason.

Chatzilla was genuinely awful though.

Not complete without Gopher.

Needs Gemini.
