Opera 12, with its insanely fast Presto engine and tab grouping that Chromium-based browsers only recently emulated.

Yes, I know about Vivaldi, but it's just not the same.

I tried Vivaldi a few times over the years, and the UI is always really slow; there's a noticeable lag with everything.

But yeah, I really miss Opera; still the best browser to date. I also really liked the Opera Dragonfly devtools.
