The Arc Browser Is Dead, but the Firefox-Based Zen Is a Great Alternative

Arc, the much-hyped privacy-forward internet browser, won't be getting any more new features. This fact was announced months ago by its developer, The Browser Company, and clarified yesterday in a blog post in which the venture capital-backed entity that built Arc announced plans to focus on an as yet unreleased AI-based browser instead.

For now, Arc will still be getting security updates, most of them inherited from the open-source Chromium project, but it's understandable that some dedicated Arc users may be looking for an alternative, and I know of a good one: the open source Zen Browser, currently in beta.

Zen is beautiful in the same way Arc is, with its elegant vertical tabs located on the left side. Like Arc, it supports multiple workspaces and offers a compact mode with no toolbars or tabs. It also offers theming, split view, and link previews. Even better, it's built on the same browser engine as Firefox—and not Chromium—meaning it supports legitimate ad and privacy blockers like uBlock Origin.

One Arc feature Zen lacks is any kind of AI integration; whether that's a downside or an upside will depend on your feelings about AI in your browsing experience.

How to get started with the Zen Browser

When you install Zen it will offer to import your bookmarks, history, and even your passwords from another browser on your system. It then ask you to choose a color scheme, and select the key tabs you'd like to pin to the top of your workspaces(). After that you can start browsing the internet, just the way you're used to.

Arc users won't need to adjust much when switching to Zen—I daresay everything will feel pretty familiar. (I personally appreciate that it shares the the command bar approach to typing addresses or searching, as it saves space when compared to an address bar that's constantly taking up space whether you're typing into it or not.)

There are a couple of ways to customize Zen. In the settings you can choose between a single, multiple, or collapsed toolbar. If you want more fine tuning, there are Zen Mods, community-made plugins that let you customize all sorts of things about the user interface. More importantly, the browser offers full support for Firefox extensions, meaning you can also browse the Firefox Extensions gallery and install anything you want.

The bottom line: Zen is a clean, speedy alternative browser. If you like Firefox but hate its UI, I recommend checking it out, and the same goes for anyone seeking an alternative to Arc that is still actively being developed.
