People feel differently about AI, and here at Firefox, we think that is completely reasonable. Something else that is completely reasonable: deciding for yourself how and when you engage with AI features. For some of you, AI is part of your everyday life, whether you are using it to summarize a large amount of information, brainstorm ideas for work, or research trips and personal purchases. Some of you interact with AI as little as possible, and prefer to keep it that way.

There’s only so much room on your screen. Pop-ups, overlays, and ads can take over fast, getting between you and what you came to do. That’s where Ad Blocker for Firefox on iOS comes in: a built-in option that blocks many third-party ads and ad-related trackers before they load, helping reduce clutter and distractions while you browse. Ad Blocker uses Apple’s WebKit Content Blocker technology and the EasyList filter list to determine what gets blocked.

Open or closed AI isn’t a fringe question anymore; it’s a live policy debate, with real consequences for who gets to build, audit, and compete in the AI ecosystem. But as that debate plays out in Washington, Brussels, and beyond, the harder questions are still very much up for discussion. What does meaningful openness actually require? Where should the guardrails sit? And who gets a say in setting them? That’s exactly the gap a group of us set out to close two years ago.

Gamers have asked for GeForce NOW support for years. Today, NVIDIA made it official, opening up GeForce RTX-powered play to Firefox on Windows. Firefox users can now stream more than 2,000 PC games from virtually anywhere, no downloads, installs, or hardware upgrades required, just a Windows PC and a browser. Cloud gaming pushes a browser in ways most websites never do. Every click and frame matters.

Firefox users were choosing Startpage long before today — to the tune of more than a billion searches a year, every one of them required some assembly: an extension, a manual setting, a workaround. Today, starting with Firefox 154, that choice becomes as easy as head to the drop-down menu, hit ‘select,’ and start searching. Startpage is now a built-in search option for Firefox users on desktop in Germany, France, Austria, Switzerland, and the Netherlands. Android and iOS are coming soon.

Browsers make it easy to start things, but picking them back up is another story. We start planning a trip or researching a purchase, and before long we’re comparing options and chasing ideas across dozens of tabs. That work rarely happens in one sitting. When we come back after an interruption, we have to figure out where we were, what we’d already found, and what we were trying to do in the first place.

AI has changed how we browse. Full stop. The real question is whether AI leads to one browser experience for everyone, or gives people more ways to make the browser work for them. Firefox was always built to give users an alternative to the status quo, and our approach with AI is no different. Much of the industry is going in another direction: Company A builds the browser → and the search engine → and the AI model → and all the surrounding services.

If you’ve ever simplified an interaction just to make a prototype manageable, you’ve probably felt the tension between what you designed and what the prototype could actually support. The risk is that when a design fails in usability testing, you can’t always tell why. Was the experience itself the problem, or was it really the prototype getting in the way: a missing connection, a laggy transition, a path you didn’t build?

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.

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.
