What is Zen Browser?
Zen Browser is heavily inspired by Arc Browser, with one core difference. It was built for those who want a Chromium alternative, but love the idea of a modern browser with a powerful sidebar, like Arc.
That said, with it being built atop Firefox, if you're moving over to it from Google Chrome or Safari, you're most notably going to notice how many browser extensions you use that don't exist in Firefox more than anything:
Only 2 of 29 extensions ported over
It's also built by a much smaller team, so you really have to just be somebody that absolutely loves Firefox, and wants to use a modern spin on that. That said, if youwant an Arc-like experience without the bugs? Just use Arc instead.
