Zen looks like Arc Browser, but Firefox-based and open-source. Exactly what I'm looking for!
The UX pattern for tabs in Arc is amazing. No, it's not just "vertical tabs". It's an innovative blend of the concepts of bookmarks and open tabs. Sort of like files: they can be open or closed, and live in a folder hierarchy.
But the development of Arc stopped half a year ago (except security Chromium updates), with a well-working Mac version, but Windows version which is barely usable and no Linux support. The creators decided to focus on some sort of "AI agent" browser.
So I came looking for alternatives that would be cross-platform, have working adblockers, and preferably be open-source. There are some "Firefox transformation" projects like ArcFox, but they are clumsy to set up and usually only copy the general look, not the actually useful features like nested folders. There are extensions like "Tree style tabs" but they work a different way than Arc.
