Started using Opera again a year ago after few years of Chrome and haven't looked back. Its even better than Firefox.
I used to use Opera as my primary browser for many years, back when it was a proper browser suite, with its own rendering engine and tons of great integrated features and configuration options. Then they dumped all that several years back to turn it into what amounts to a Chromium reskin with a handful of integrated extensions. It's okay, for what it is, and I have it installed for occasional use, but it's a pale shadow of its former self.
