If anyone’s looking for a browser with deeply integrated vim key bindings then check out qutebrowser. I’ve been using it for about a month now and it’s pretty great. Only downsides for me are lacking support for my yubikey, and questionable security. I’m not saying the security is necessarily bad (I think the actual browser is based on chrome), just that I don’t have as much confidence in it as I would in stock chrome or Firefox.
The adblocking/script-blocking capabilities (described in #9 and #10 in their FAQ: https://qutebrowser.org/doc/faq.html) are extremely weak and inconvenient (and their claim about the negative impact of adblocking is outright false).
Those are probably the two most important capabilities for security, so the lack of them definitely means I'd never want to use it for general browsing. I'd much rather deal with weaker keybinds than sacrifice that much on the security and privacy side.
I know it's a pain for new browsers to support, but I can't imagine myself running any browser right now (even experimentally) that can't install UMatrix and UBlock Origin.
If you want me to try out your browser, you have to support the WebExtension API -- you can support other APIs in addition to that, but WebExtensions are a minimum requirement. I guess Chromium doesn't bundle them, so it's harder for smaller browsers to add the same capabilities?
Supporting WebExtensions isn't possible without QtWebEngine (the library qutebrowser uses) doing so. That might happen some day, but will probably still take a while.
It's easier to claim that a real adblocker is a net negative for performance while implementing in a slow language than admit that they can't realistically do better this decade due to the complexity of the task and the fact that it's basically one guy's part time project.
