To all Mozilla users: I was once like you. I stuck to Mozilla (or Seamonkey) for years and years and years. But recently I realized that it had become a resource hog, and I went a-searching for another browser. And I found it. And it’s the best web browser in existence. It is Opera. It takes a bit to learn the quirks, but once you do, you realize it is the most user-friendly browser out there.
I’ve tried Opera several times over the years since I first heard about it here at FR. For me, it’s never been any improvement over FF whatsoever. And, in fact, sometimes it’s just weird.
