There are also surf https://surf.suckless.org/ and qutebrowser https://qutebrowser.org/, both based on webkit.
Is there a well-maintained fork that fixes these issues? The main repo[1] hasn't seen updates in over a year now. I read that development slowed down after the main maintainer left suckless, but I'm hoping the community will pick it up. It's an excellent minimal browser.
There's zsurf based on QtWebEngine/Chromium too, FWIW: https://github.com/SteveDeFacto/zsurf
You can use it with QtWebKit instead, but given that's based on a 2016 WebKit with no process isolation or sandboxing, I wouldn't recommend it.
