Inside Mission Nova, Firefox’s largest redesign in years
Abstract created by Sensible Solutions AI
In abstract:
- PCWorld stories Mozilla is launching Mission Nova, Firefox’s largest interface redesign in six years, that includes AI integration and enhanced customization choices.
- The overhaul addresses Firefox’s declining 3.45% US market share by integrating privateness instruments like Monitor and Relay immediately into the browser.
- Firefox goals to distinguish from Chrome and Edge by providing consumer management over AI options whereas sustaining privateness focus.
Virtually any browser is at a elementary drawback when it comes to customers and affect (that’s, until you’re Google or Microsoft). However that hasn’t stopped Mozilla, which is reshaping its Firefox browser in a “Mission Nova” overhaul, whereas threading the needle between AI, privateness, and extra options.
The easy questions is that this: Why aren’t extra folks utilizing Firefox and what may persuade them to return again?
It’s loads to soak up, and the hour PCWorld’s Alaina Yee and I spent with the top of Firefox, Ajit Varma, flew by. One of many elementary issues browser builders like Firefox have is that there’s completely nothing stopping customers from taking a number of seconds, downloading the free Firefox browser, and shifting forward.
However they don’t. Statcounter says that solely 3.45 p.c of American customers use Firefox, and that’s down from years previous.
That appears to trouble Varma a bit, who’s making an attempt to arrange customers for a flurry of latest options he says will all be accomplished in about two months.
“Earlier than I joined, from the surface wanting in, I believed the issue was imaginative and prescient,” Varma mentioned, after a bit greater than a 12 months on the job. “Once I got here in, there was thought after thought. Right here’s an working system. Right here’s cellular. The issue was actually execution.”
So why is Varma right here? To make the case that it’s time to attempt it out once more.
“I don’t assume that we’re doing a ok job of telling our story,” Varma mentioned. “I’d fee product improvement an A, however our storytelling is perhaps an F.”
The Firefox “Mission Nova” revamp sounds slightly wild
Firefox was launched in 2004 (21 years in the past!), peaking with a 32 p.c market share as archived by Wikipedia. Over time, the browser grew to become an early champion of privateness, blocking pop-up advertisements, and serving to to advertise the idea of extensions. It was launched as open supply, not like a lot of its opponents, and nonetheless makes use of the Gecko rendering engine that differentiates it from most of the rival browsers primarily based upon Chromium and its Blink rendering engine.
“One of many good issues about having Gecko is that, not like plenty of the rising AI browsers, they form of all look the identical,” Varma mentioned. “These are all constructed on prime of Chromium, whereas we have now this flexibility to create a extra fashionable browser.”
That “fashionable” browser revamp is known as Mission Nova, which is able to replace the interface for the primary time in about six years. Early prototypes have leaked out (together with rounded corners), however it seems like customers might need the choice to tweak and tweak some extra. How a lot of this will probably be accessible within the settings? How a lot will probably be accessible by way of *gulp* AI?
It’s laborious to say, and it seems that a number of choices would possibly nonetheless be on the board. The query I requested was about folks within the wild vibe-coding browser extensions, and whether or not one thing like that may sync with Varma’s imaginative and prescient. However perhaps AI will imply one thing extra?
“Like each tech firm, we’re actually excited in regards to the velocity will increase from AI, and so we have now plenty of inside prototypes which are up and working, and extensions is one in all them,” Varma mentioned. “However plenty of issues we’re staring consists of questions like: Are you able to customise your homepage? Are you able to add widgets? Can you modify your background in no matter means you need?”

“Undoubtedly, the concept of extensions and simply customizations on the whole is: are you able to create extra of like a pure language interface that lets folks do every little thing they need?” Varma added. “For instance, we introduced an replace that we’re doing to our design, which is known as Mission Nova. And lots of people didn’t just like the rounded corners modernization. Now, we are able to let folks choose how spherical they need their corners. Folks care, so we put it within the settings.”
“There’s actually no motive for anybody to say, ‘That is your browser; you are able to do no matter you need,’” Varma added.
What else can customers count on? In accordance with Varma:
- Bringing again Firefox compact mode
- Higher tabs, higher tab administration, and higher settings
- Privateness options, together with an improved VPN and Relay electronic mail masking
- An improved new-tab expertise, together with widgets
- “Sensible Home windows,” which will probably be Firefox’s first foray into bringing a few of “AI” intelligence to the consumer
Tiptoeing into AI
Mozilla’s Firefox group has the identical downside as another app developer: AI generally is a device, however one {that a} subset of customers really feel very strongly about. Final November, the group talked about “AI home windows” or “good home windows,” the place Firefox tried to string the needle. If customers typically work together with AI inside the browser, ought to the browser be redesigned to accommodate it? Put one other means, if a consumer can choose a search engine, shouldn’t they be allowed to pick an LLM, too? They assume so.
It’s a delicate topic. A current model of the browser permits customers to activate (or off) particular AI options akin to translations. You can even relegate an AI LLM to a sidebar or you may toggle off all AI options completely with a single swap. Customers take this very severely, Varma mentioned. He remembers one consumer interplay:
“They mentioned, ‘No, there’s a button that claims Proceed,’” Varma mentioned. “I defined that it’s opt-in. However they insisted it was a darkish sample.” They anticipated a toggle or a swap to verify their selection.

However Varma additionally acknowledged that the idea of a browser is considerably outdated.
“If you take a look at the time period browser, it’s very antiquated within the sense that there’s static content material, and after I click on on the content material, I get to the subsequent hyperlink,” Varma mentioned. “With apps, it grew to become extra bidirectional. There’s extra wealthy engagement with AI.”
“As a substitute of being a browser, it’s turning into a generative system, however it’s not doing it in a detrimental means that stops the particular person’s incentive from creating the content material within the first place,” Varma mentioned.
The distinction between Firefox and different apps is that Mozilla has no incentive to prioritize a selected app or service. A selection display may ship quite a lot of fashions — most likely curated by Mozilla, Varma mentioned — or nothing in any respect. (Perplexity AI simply appeared.) Varma dismissed Edge as “a Copilot app,” and Chrome as “a Gemini app.”
“I feel that’s what occurs when firms really feel like they’ve gained, after which they’ve this new aim. That’s after they begin making modifications that aren’t within the consumer’s greatest curiosity,” Varma mentioned. “We don’t have another aim at Firefox [beyond], aside from to construct the very best browser and protect an open Web.”
Mozilla does use AI instruments to construct Firefox, Varma acknowledged. “We’re utilizing [AI] instruments, however we do have a stance that each piece of code in Firefox must be touched [reviewed] by a human,” he mentioned.
Paid Firefox is occurring
Mozilla and content material creators share a really imprecise similarity: a few of their earnings comes from search engines like google and yahoo.
In 2024, the final 12 months Mozilla publicly printed earnings statements, the corporate made $585 million (about 86 p.c) of its income from Google as the first search engine. But when consumer exercise strikes away from search to AI-driven LLMs, what then? Varma mentioned that they’re preserving their choices open — offering a selection for customers additionally equates to decisions for the corporate itself.
“We don’t but understand how we are going to monetize,” Varma mentioned. “Possibly we’ll have a subscription. Possibly we’ll do a distribution deal. We’re preserving our choices open as a result of we nonetheless need our merchandise to be consumer-led.”
Varma additionally mentioned that the on-again, off-again relationship with companies is outwardly on once more, with an enterprise model of the browser in place. If that sounds acquainted, that’s as a result of Mozilla was speaking about this again in 2011.

“We’re engaged on an enterprise model of Firefox,” Varma mentioned. “It’s truly one of many issues that I’m very enthusiastic about. We’ll at all times have a free model, however the enterprise model is for firms and governments in elements of the world which are apprehensive about their dependency on huge tech. Plenty of that is across the banner of digital sovereignty, and so they’re asking if we are able to present small-tech or open-source options. And so that is one factor the place we are able to provide related options, however then, you recognize, there are providers that individuals are prepared to pay for, like companies and stuff.”
Mozilla additionally has some historical past in an upsell mannequin. Model 149 of the browser added a free VPN with a utilization restrict, however Mozilla VPN protects a number of units, not simply your browser. It’s $4.99 per thirty days. Varma mentioned that the browser-based VPN service requires logging in with a Mozilla Firefox ID, and that ID is tied to the quantity of knowledge the VPN consumes, or 50 gigabytes max. In any other case, the corporate doesn’t observe your shopping historical past.
“The moment that the visitors is served, it [the data] is now not retained,” Varma mentioned.
Within the coming months, you’ll see extra VPN endpoints within the nations Mozilla serves, Varma mentioned, although the corporate is working with companions. It’s not clear what number of entry and exit factors per nation Mozilla will construct out, however Varma mentioned that the corporate shouldn’t be making an attempt to do “sketchy” issues like put a number of endpoints in a datacenter and place them as separate places.
Firefox first, Firefox without end
Lastly, Varma pledged that extra of the integrations you’ll see within the browser will make sense. Traditionally, merchandise at Firefox have been “siloed,” or designed in their very own little setting. Now, merchandise just like the Relay electronic mail masking service will probably be prolonged past 5 masks. Monitor, which helped scrub private data from knowledge websites, survived the 2024 layoffs, and redirected some improvement efforts away from privateness and into Firefox correct. Monitor will probably be built-in into the Password Supervisor, Varma mentioned.

Nonetheless, the purpose stays unchanged: Firefox first.
“That was a mistake on the Firefox aspect that we’re now fixing, and that truly — VPN being the primary instance — all that will probably be very nicely built-in inside the subsequent three months,” Varma mentioned.
