It's an Arc-Browser clone WIP which uses Firefox as base. It's everything I would want from a browser.
Pros:
- Open Source
- UI-First Approach means it's working towards a modern browsing experience like Arc
- Firefox as base so all Firefox Extensions like Adnauseum/Ublock work on it
- No threat of MV3. Arc has stopped blocking ads for me hence I will no longer be using Chromium at all. Adblocking works like a charm on Zen.
- Highly customizable with a very fast development cycle.
Cons:
- It's in Alpha so expect Bugs and less features
- Still missing some features from Arc like Peek and Command Bar
I would recommend trying out this browser @ https://zen-browser.app/
When I saw that and "container tabs", I thought it was going to have a good implementation of vertical tabs, but it really doesn't. No easy folders, no organizational features...If they add some stuff that makes it meaningfully different from Firefox, I might give it some thought, but right now, there's really no point. Better keyboard shortcuts or something would even make me switch, but that bar seems useless now.
