Tabs pile up fast on mobile. Imagine you’re planning a summer barbecue, and you start by searching for the best rib recipe. Twenty minutes later, you’re 17 tabs deep: comparing marinades, debating side dishes, checking the weather, making a grocery list and adding songs to a playlist.

None of those tabs are organized. They’re mixed in with everything else you’ve been browsing, making it hard to keep track of what you’re saving for later.

Now you can group related tabs in Firefox for Android, keeping them together in labeled, colored groups so you can actually find what you need when you need it.

How it works

Drag one tab onto another, or select a few and tap “Add to group.” Name it, pick a color, and you’re done.

Each group appears as a single card in the tab tray rather than a dozen separate tabs. You can open it, rename it, recolor it, or delete it whenever you want. Search still finds tabs inside a group, too.

So when you’re standing in the produce aisle looking for that rib recipe, you won’t have to scroll past dozens of unrelated tabs just to find it. Everything for your barbecue is organized together in one place, ready when you need it.

Finally sorted, as it should be

Tab grouping was the most requested feature from Firefox mobile users in 2025. And we get it: your tabs shouldn’t get harder to manage the more you use your browser. Download the latest version of Firefox for Android now to try Tab Groups, with iOS support on the way.

You’re planning a trip. Reading an article. Following a recipe.

Then a question pops into your head. Sometimes it leads down a rabbit hole – with more searches, more tabs and plenty to explore. Other times, you just need a little context so you can get back to what you were doing.

That’s why we’re introducing Quick Answers for Firefox on iOS.

With Quick Answers, you can ask a question using your voice and get a concise answer. Just open a new tab, long-press the voice button and ask.

For example:

• “What does mellifluous mean?”
• “What is 95 degrees Fahrenheit in Celsius?”
• “What’s the difference between suede and nubuck?”

If a quick answer is all you need, you’re done.

If you want to dig in deeper, the links to supporting sources are there for exploration.

Built with transparency and privacy in mind

We’ve built Quick Answers to be transparent about how it works and what data is shared.

Voice is processed on your device using Apple’s speech recognition technology. No raw audio is stored or sent to the server, and Firefox doesn’t share your browsing history or personal context with the AI model. Only the transcribed text of your question is sent to generate an answer. You can turn the feature off at any time in Settings → AI Controls.

Quick Answers is starting to roll out today to Firefox for iOS users in the U.S. using English.

Oh, and if you’re wondering…

• Mellifluous means pleasant and musical to hear.
• 95 degrees Fahrenheit is 35 degrees Celsius.
• Suede is made from the underside of the hide, while nubuck is made from the outer side and buffed to create a soft, velvety texture.

Today, we’re excited to announce the Preview of Containers in Firefox version 153, which lets you keep separate parts of your online life (work, shopping, personal, banking) logged into different accounts in the same browser window, but keeps your cookies and ad tracking isolated inside each container.

This means that stuff you do in one container isn’t seen by other containers. No longer will you search for a new hat to wear to a party, only to be inundated with ads for hats at every twist and turn on the internet for weeks to come.

For almost a decade, many of you have relied on our Multi-Account Containers extension to keep work, personal, and privacy-sensitive browsing separate without needing multiple browsers or profiles. 

We’ve heard your feedback and understood the value you find in that separation. Now, we’re bringing the power of the Multi-Account Containers extension directly into the heart of Firefox for all to benefit from.

Why bring Containers into Firefox?

Whether you’re managing multiple social media accounts, separating work projects from personal shopping, or simply keeping your banking activity distinct, Containers are designed to help you organize your digital space. By making Containers a native, first-party feature in Firefox 153, we are:

• Making it visible by default: You no longer need to hunt for an add-on to get started. Containers are built right into your browser, ready to help you manage your context from day one.
• Simplifying your workflow: We’ve focused on making it easier to open, create, and manage your containers from the places you already browse.
• Preserving what you love: For our long-time users who have relied on the add-on, the native experience is designed to maintain the core functionality, flexibility, and visual identity you depend on.
• Driving continued investment into the future of this feature, ensuring it lives on as a first party citizen of Firefox.

What to expect in the Preview

In this preview release, you can:

• Open tabs in specific containers: Keep your browsing activity isolated by context.
• Customize your workspace: Create and manage containers with your own names, colors, and icons.
• Manage settings easily: Control your container setup directly from the Firefox settings surface.
• Get Started: Right-click any tab or long-press the new tab (+) button to open a container tab — or head to Firefox Settings to create your first container.

If you’re already using the Multi-Account Containers, there’s nothing special you need to do. Not all of the features of the add-on are available in the first-party version of containers just yet, we’re still building them out.  You can continue to use the add-on alongside the built in containers, no need to uninstall the add-on.

This release represents our first step in making Firefox more adaptable to how you actually live and work online. While this is just the beginning, we have plans to refine this experience and build a foundation for future features that make context separation even more seamless.

Join the Conversation

We’re eager to hear how this native experience fits into your daily routine. As you explore the new Containers Preview in Firefox 153, please let us know what you think by posting your feedback in this Mozilla Connect thread. Your feedback helps us shape the future of these tools and ensures we’re building features that truly matter to you.

The post Experience Better Browsing: Introducing Native Containers in Firefox 153 appeared first on The Mozilla Blog.

Two years ago Mozilla asked two leading experts on deceptive design, Dr. Harry Brignull and Cennydd Bowles, to look at how Microsoft was treating people who tried to use a different browser on Windows. Their report, Over The Edge, documented a pattern of design choices in Windows, Edge, and Bing that nudged, pressured, and at times tricked people into using Edge.

This morning, the same researchers are publishing Over The Edge 2.0. They retested the same questions across Windows 10 and Windows 11, and added two new dimensions. First, how does Microsoft’s approach change from one jurisdiction to another? They assessed Microsoft’s tactics across four regions: the USA, India, the UK, and Germany, as a representative country in the European Economic Area. Second, they examined how AI features, specifically Copilot, are being used to shape the same outcomes the original report identified.

Their conclusion is short. Microsoft still does not allow users to download, set as the default, or keep using alternative browsers without harmful interference. The patterns are documented, and they meet established definitions of coercion, deception, and manipulation.

There is one bright spot. In Europe, where the Digital Markets Act applies, some harmful design tactics are gone. The Bing ‘All you need is right here’ panel and its trick wording. The nagging Windows 10 ‘You’re almost done setting up your PC’ journey. The Copilot data toggles that default to “On” in the US and India, by contrast default to “Off” in the EEA and the UK. Same Windows. Same Edge. Same Copilot. Different design choices, because the law required them.

That is the heart of the report. Although the EEA product still has obvious harmful design patterns, Microsoft has built a fairer user experience for browser choice. It has shipped that experience to one region. Everywhere else, including the US, the UK, India, and Brazil, harmful design patterns continue. This is an active choice – and one that can be made differently.  

The findings are the researchers’ own. Mozilla commissioned the work, and the report discloses that role, but the methodology, the screenshots, and the public journey database at edge.brignull.com let anyone check the evidence for themselves.

We make Firefox because we believe the web should serve people, not platforms. Firefox is independent, built by Mozilla, and designed around what is best for users, not what increases lock-in.

Open source AI has crossed a threshold. For years the debate has centered around whether open models could ever compete with closed ones. This is no longer a debate we should be having. Today Mozilla is publishing its inaugural State of Open Source AI report, built on new analysis and a global survey of 950+ developers, showing that open models are no longer playing catch-up. The performance gap with top proprietary systems like ChatGPT and Claude has narrowed to just 3%, while costs have fallen up to 50x in three years.

But the report also surfaces a harder truth. Open models now power roughly a third of real-world AI usage, but capture only 4% of the revenue. So while the value is there, it just isn’t flowing back into the open ecosystem that made it possible. Meanwhile, the geopolitical picture is shifting fast.

Asia is racing ahead

China and East Asia now lead the world in open source AI adoption, at 89%, far ahead of the West, treating open source as a cornerstone of national strategy. Governments elsewhere are responding, with 12 new national AI strategies launched last year, and 47 countries now restrict foreign processing for critical workloads. The EU, Canada, and India are backing open ecosystems with real public investment, treating AI infrastructure as a strategic asset.

Developers want open models, but they can’t always ship them.

For developers, the appetite for open source is there, and cost and privacy rank as developers’ top reasons for choosing models. But wanting to use open models and running them in production are different things. 79% of developers use open models, yet only 51% have deployed them in production, versus 63% for closed models.

As Álvaro Ruiz Cubero of SlashData, which fielded the survey for Mozilla, put it: “this gap indicates that there is not an issue purely of model quality, but of missing infrastructure. Deployment rates for open models barely increase with company size, highlighting a lack of mature tooling and support. At the same time, buyers are prioritising licensing terms (31%) and ownership (26%), signalling a clear shift toward control and flexibility over raw capability.”

The real battle has moved beyond the model

Perhaps the most important finding may be the least obvious. The layer that matters most isn’t the model. It’s the agentic harness: the software between people and models that decides what an AI system can see, remember, and do. Changing the surrounding software can affect performance more than switching the model itself. Whoever controls that layer controls how AI behaves in the world.

Right now, that layer is being built with very few guardrails. Users approve AI agent requests by default up to 93% of the time, with so-called “consent fatigue” going largely unnoticed.

“Open source AI has reached a turning point,” said Raffi Krikorian, Mozilla’s Chief Technology Officer. “It’s no longer about expanding access to models; it’s about who has the power to shape, audit, and improve them. Without investment in the infrastructure, tooling, and governance around open models, we risk locking in a system where only restrictive, closed AI can scale – and that doesn’t serve the public interest, or sovereignty over tech policy decisions.”

Be owners, not renters

Open models offer what a subscription never can: owning your infrastructure instead of renting someone else’s. Companies like Microsoft and Uber are already rethinking their reliance on paid, closed AI tools as the bills add up. The economics are shifting and so is the thinking. 

If you’re a CTO, a policymaker, a developer or an investor, this is the report for you. Read it, share it, and help build the infrastructure to make openness usable, not just possible.
