Zen rips off all the best bits of Arc, but skips the AI and bloat.
I know many of you are mourning the loss of the Arc browser, and I get it. It felt like the first app in a long time to really offer a new approach to browser design. Atlassian bought the company last year and shifted its focus to developing Dia, its even more AI-focused browser. And soon enough, Arc will officially be no more, leaving dedicated users in a lurch. But I abandoned Arc quite some time ago for the Zen Browser and haven’t really missed it. If you’re willing to deal with some minor inconveniences, I think you’ll find Zen is the Arc replacement you’re looking for.
Zen unabashedly rips off all the best bits of Arc. Visually, they’re almost indistinguishable. It has the launcher-like pinned sites, tab bar on the left, siloed spaces, and mods that let you customize the browser’s UI to your liking. It takes the bits that made Arc’s interface feel fresh, then strips out everything that made it bloated and drove me into the arms of another.
Most notably, Zen is AI-free.
There’s no agent in a sidebar hounding me to let it handle tasks. I’m not worried about Zen training an LLM on my browsing activity. It’s just a web browser.
Zen prides itself on its privacy features: “Beautifully designed, privacy-focused, and packed with features. We care about your experience, not your data,” it proudly proclaims. Now, I’m no fool. I know that nothing I do on the internet is really private, but with Arc, it always felt like my data was an integral part of the business plan. That’s not the case with Zen. It’s a free and open-source project that relies on volunteers and donations.
In addition to Zen Mods that can do anything from tweak the look of an active tab to overhaul how PiP videos are handled, you can also install Firefox extensions. Yes, you can install Chrome extensions in Arc, but anecdotally, I’ve found that Zen handles extensions better. Both Zen and Arc are different enough from a UI perspective that not all extensions display properly, but Zen offers more workarounds.
Zen also just kind of lets me focus on the task at hand. Links open in “glance” view, which is a temporary pop-over tab, which is really great when you’re doing some window shopping or light research. If I want to open it in a proper tab, it’s just a click away. Zen also has a floating bar that pops up whenever you press Command+T or CTRL+T. From here you can launch a new tab, switch to an existing tab, perform a search from the search engine of your choice, and even trigger an extension.
Zen isn’t perfect. I love its clean UI and organizational features, but it can’t play DRM-protected video content right now. That means Netflix, Spotify, HBO, Disney+, and more do not work in Zen. The Zen Team is working to obtain a Widevine license from Google. In the meantime, I use Chrome when I want to watch a movie, which is fine. Zen is built on Firefox, and Firefox’s Web MIDI support is lacking. So I have to fire up Chrome semi-regularly anyway.
I also miss Arc’s Boosts in some cases, but I’ve learned to accept the web as it is. Zen implemented a similar Boost feature in May, but it’s not super obvious and, if there is an official, easily browsable repository of installable Boosts, I’ve yet to find it. Instead, you have to tweak individual sites’ appearance yourself.
If you tried Zen a long time ago and were turned off by its buggy early builds, rest assured it’s come a long way. Look, if you are all in on Arc’s AI features, Dia is probably more your speed. Personally, I always loved Arc’s interface, but never really dug the vibes. Zen just feels right.
Update October 25th: Added information about Zen’s implementation of Boosts.

An update to Firefox’s AI browsing experience can draw from your open tabs to help you fill out forms.
An update to Firefox’s AI browsing experience can draw from your open tabs to help you fill out forms.
Mozilla is updating Smart Window — Firefox’s AI-powered browsing experience — with a new feature that can help you fill out online forms based on your open tabs. As an example, Mozilla says Smart Window can pull information from your online portfolio or LinkedIn page to paste your work history into a job application.
You can try out this feature by clicking into a form with at least four text fields. From there, you’ll see an option to “Fill from sources,” which will show all of the tabs Firefox will draw from. You can then select or deselect tabs that you want Firefox to use, and the browser will generate suggestions based on the information in them. This feature currently supports text fields on web forms, but Mozilla is working to add support for dropdown menus and PDFs. Mozilla notes that data from your source pages is shared with Google’s Gemini 3.1 Flash Lite, the AI model that generates the text suggestions.
Along with this update, you can now ask Firefox’s Smart Window to watch a certain webpage for sales, new job listings, and other updates. You can set up a task by typing “/watch” in the Smart Window chat, describing what you’re looking for, and adding the webpages you want to watch. Firefox can then check for updates on a daily or weekly basis, but only when the browser is open.
When Firefox detects the change you’re looking for, it will send you a notification through the Tasks button on the toolbar, or on your desktop (if you have desktop notifications enabled). Firefox will pause watching for updates if it doesn’t detect a change after 60 days, before stopping them completely after 90 days.
These two features are rolling out to the Smart Window beta on desktop in the US and Canada. They’ll be available in other countries in the “coming months.”

The Genie 4 world model offers more realism and can create audio to accompany its interactive worlds.
The Genie 4 world model offers more realism and can create audio to accompany its interactive worlds.
Google announced today its Genie 4 world model for generating interactive experiences using AI. The company says the model has four main updates: It allows for more realistic worlds, lets users update an experience in real time with a natural language prompt, can generate audio, and uses Gemini 3.8 Flash under the hood to help with its simulations. It also can create experiences that are about two minutes long, up from one minute for the previous Genie 3 model.
Google is pitching Genie 4 as a tool that could be helpful for things like pre-visualization for filmmakers, prototyping game ideas, and making training scenarios for robots. But the company warns that, as simulations run longer, details and object permanence can shift over time.
I haven’t been able to try Genie 4 for myself — it’s launching first as a “research preview” to “trusted testers” — so I can’t tell you how it compares to the Genie 3-powered Project Genie, which I used to generate bad Nintendo knockoffs. But here are some examples from Google demonstrating what’s possible with the new model.
Genie 4 will be “coming soon” to Google AI Ultra subscribers, Google says, and the company has opened a waitlist where you can apply to be able to try it in Project Genie.
