Please, no. I think part of the reason Fastmail has been able to focus on the user experience is because they are independent. I don't want them acquired, disbanded, and dumped. It's the best paid service I've ever used.

There's a joke at Mozilla that "Opera did it first". Pretty much every new feature in Firefox, Chrome, etc has appeared first in Opera.

Funny how far Opera has fallen these past few years. Years ago it was setting trends with tabs. Now it's yet another Chromium-based browser.
