    It still needs improvements. Initially, I started loving it while using it alongside of WaterFox and FireFox. But then I realize the bugs with its Splitting feature. Its difficult to create splits, although it is very useful. In windows, sometimes it spawns multiple instances/windows of itself even when I tried to do a split. In the background, it still tries to access some tabs, which were closed in previous session. And due to that, it was not getting closed even when I clicked on Close Tabs...

Zen browser is an amazing browser. I switched to it from Arc after Chromium started suppressing adblockers. It has so many good features and is made by just one independent developer, which makes it an awesome alternative to Chromium-based browsers.

In the background, it still tries to access some tabs, which were closed in previous session. And due to that, it was not getting closed even when I clicked on Close Tabs on the Exit message. Finally shifting to WaterFox. (I will evaluate LibreFox in the mean time)

Love it but on Linux (Hyprland) it spawns new windows which can't be closed.

Great browser! I haven't made it my default one on my main computer yet, mainly because it's still new. However, it is very fast and manages to work with google meet, something Brave fails miserable to do (at least for me). Also, the slick interface makes it a great option for any minimalism-minded user. On my raspberry pi, I have it as the main browser.

Just tried it. Having used Arc before, Zen isn't as polished in design & polishing details but is 90% there. It felt good to use, as good as Arc. Web browsing & loading speed on Windows feels way faster than Arc.

It's extremely smooth, slick, responsive, well designed, beautiful, and delightful to use, which is a very pleasant surprise as these aren't really traits people typically associate with open-source software.

Zooming & scrolling is smooth. Trackpad gesture (on Windows) felt slick just like in Arc. Blurred glass, bouncy & fluent animation, modern color picker, consistent branding. Zen simply blew me away. If no one had told me, I wouldn't have thought this was an open source Firefox-based browser.

Feels nicer to use than even Firefox itself, which this is based on. If you (like me) want to avoid the Chromium monopoly, or want to use uBlock Origin after Manifest v3 rolled out to Chromium, but are put off of Firefox's unpleasant redesign ever since Proton UI & lack of modern-day productivity feature, then this might be for you.

There's the lack of folders/tab groups, but they're working on it at the time of writing, with screenshots going around. It also lacks linking Workspaces to a seperate profile, but this can be mitigated by Firefox's own Container Tabs.

The only downside is that it eats a bit of RAM. Ate 4.5 GB with just a couple of web apps open.

Best browser at the moment imo. If you tried it 6 months or longer ago try again. It has become stable enough for daily use and the UX is really, really good.

The feedback loop from community to development is quick, that's the coolest part here. It actually feels community-driven unlike almost every other browser.

What is Zen Browser?

Zen Browser is an open-source software based on Mozilla Firefox, focusing on privacy, adaptability, and aesthetics. It uses vertical tabs, like Vivaldi, Microsoft Edge, Brave, and Arc Browser, but plans to add horizontal tabs in the future. Unique features include Split View, Zen Sidebar, Zen Glance, and workspaces for tab separation. It prioritizes user data protection with security features like tracking protection, support for the Online Certificate Status Protocol (OCSP), and strict SSL standards. It's built on the latest version of Firefox, inheriting its security updates.
