I did try Otter in the past when I was looking for the Opera replacement, never really liked it. It seems like it’s pretty dead…last update was 2 years ago. And speed was never really my priority for the browser anyways. I’m not really looking to replace my browser, I’m happy with Vivaldi, I just like to check what else is there. I was happy to see that there is a browser based on gecko that seems to be going in the similar direction as Vivaldi.
