Looking for an alternative to Zen Browser?Compare Firefox, LibreWolf, Floorp, Waterfox.Compare alternativesZen Browser builds on Firefox and places tabs in a vertical sidebar. With Spaces, you keep different topics together. Split view helps when you want to compare information or follow an instruction next to a web app.
You can customize the interface with Zen Mods and synchronize browser data via a Mozilla account. The public version still bears a beta designation. This makes it wise to keep your existing browser and a reserve of important data available when you try Zen as a daily workplace.

If you want to switch within the Firefox family, look at the default settings in addition to extensions. Some variants focus on privacy, others on vertical tabs or more setting options. Importing bookmarks doesn't automatically mean that all your settings and saved sessions will go along.

Our verdict
Zen is especially attractive if you like working with vertical tabs and keeping multiple topics open at the same time. The sidebar and split view together form another way to use your browser. Those who want to keep the trusted horizontal tabbar should adapt to this.
Before a complete switch, check your video services and other indispensable websites. Especially in secure streaming, a second browser on Windows or macOS is often needed. Start with a limited set of Spaces and then add mods. This allows you to assess whether the layout really makes your work easier and to recognise more quickly which adjustment might cause a problem.
