Mozilla has taken an important step in its strategy to put Firefox back at the center of the conversation about privacy and user controlWith the arrival of Firefox 149, scheduled for March 24, the browser incorporates a free integrated VPN along with a good number of design changes, productivity features, and new user-controlled artificial intelligence options.
This move aligns with the direction set by the company's new leadership: to transform Firefox into more than just a browser, strengthen revenue streams without compromising personal data, and offer a genuine alternative to Chromium-based solutions. In this context, the VPN at no extra cost It becomes the most striking novelty, although it comes with nuances and limitations that should be kept in mind, especially from Spain and the rest of Europe.
A free VPN within Firefox: how it works and what it offers
The big new feature in Firefox 149 is the inclusion of a Integrated VPN directly in the browserTherefore, there's no need to install external applications or third-party extensions. Technically, it's a system that routes Firefox traffic through a proxy operated by Mozilla, which hides the real IP address and disguises the location while browsing.
According to the organization, the service will start with a limit of 50 GB of data per month For each user, this is a fairly generous amount for use focused on web browsing, searches, social media, or online transactions. To take advantage of it, you will need to log in with a Mozilla account, which allows that data quota to be associated with a specific profile.
It's important to emphasize that this is a solution limited to the browser itself: the VPN only protects the traffic passing through FirefoxThe rest of the team's programs or services —streaming customersGaming applications, external downloads, or standalone messaging tools—will continue to use the normal connection without that encrypted tunnel.
Furthermore, the free service is not intended to compete directly with a traditional paid VPN. It does not include, for example, the option to manually select the country or server, something common in commercial services used for bypassing geographical blocks streaming or other types of content. Instead, Firefox will automatically select the most suitable server, prioritizing performance and stability.
The infrastructure for this new privacy layer will be hosted in Mozilla's own servers distributed across different regionsAnd it doesn't reuse the network of the paid Mozilla VPN service (operated in partnership with Mullvad). It is, essentially, a separate product, encapsulated within the browser and designed for a simple experience without too many advanced options.
Privacy and trust: advantages and outstanding questions
One of the most repeated arguments by Mozilla is that its VPN is "built upon our data principles"The company insists that its offering differs from many free third-party VPNs, which often sustain themselves by collecting usage data or introducing opaque practices to monetize the service.
For those wary of free VPNs, the fact that they are managed by an entity with a track record in privacy protection can be a plus. The idea is that traffic is routed through a proxy that should not record or resell data, aligned with the foundation's data policy. Even so, several technology analysts have pointed out that the key will be to verify whether it undergoes independent external audits and if these are communicated clearly.
In parallel, it should be noted that Mozilla already maintains a separate paid VPNIt's geared towards those who need a comprehensive service that covers the entire operating system, with more configuration options and, generally, fewer restrictions. Therefore, the free version integrated into Firefox is intended more as an extra layer of privacy "for everyday use" than as a direct replacement for a professional solution.
For reasonable use—browsing, conducting business, participating in social networks, or avoiding excessive tracking—the 50 GB per month These limits are sufficient. However, if the plan is to stream in high quality, download large files, or use the VPN for very intensive tasks, this traffic limit can quickly fall short.
Geographic availability: what's happening in Spain and the rest of Europe
One of the less favorable points, at least in the short term, is the limited initial availability of the service. The free Firefox 149 VPN will launch first in the United States, France, Germany, and United Kingdomexcluding —for now— Spain and other European countries.
Mozilla has not set a specific date for its expansion to other markets, beyond indicating that its intention is expand the rollout to more regions as the service matures. This means that, although Firefox 149 will still reach Spanish and European users with the rest of the new features, the option to activate the VPN within the browser may not yet appear in all territories.
From a regulatory and data protection perspective, the organization insists that the solution's design aligns with its transparency commitments. However, until the feature officially launches in Spain, users will have to continue using [other methods]. External VPNs or the paid version of Mozilla if they are looking for similar system-wide protection.
In any case, the arrival of this functionality sends a clear message to the European ecosystem: browsers are increasingly competing in the field of built-in privacy as standardwithout relying so much on third-party add-ons, something especially relevant in a context of greater sensitivity regarding data tracking and exploitation.
Split View, tabbed notes, and more tools for better workflow
The VPN doesn't come alone. Firefox 149 incorporates a series of features geared towards improve productivity and organization without requiring the installation of dozens of extensions. Among them, the new split-screen view stands out, known as Split View, which allows two web pages to be displayed side-by-side within the same window.
This split view is especially useful for compare content, consult documentation while writing a textThis allows you to follow a tutorial while performing the steps, or check banking information without constantly switching tabs. Until now, this type of use was more associated with browsers like Vivaldi or with separate window combinations.
Another interesting new feature is the notes associated with tabsThese are known as Tab Notes or quick notes. The idea is simple: add short reminders or comments directly linked to a specific tab, so that when you return to that website later, the notes are still there, allowing you to pick up where you left off.
These features are in addition to an improvement of the Firefox Settings screenThe browser now offers clearer navigation, better-structured sections, and an internal search engine for quickly finding options. For those who fine-tune their browser settings—tracker blocking, permissions, appearance—this change should significantly simplify the process.
Overall, Mozilla's goal is to reduce so-called "extension fatigue": to make many of the tools people use daily—from split-view to note-taking or configuring AI—available natively, without relying so heavily on third-party maintained add-ons.
Smart Window and AI control: optional, not mandatory help
Alongside these more visible new features, Firefox 149 continues to roll out its commitment to optionally integrated artificial intelligenceThe AI ​​Window, formerly known as AI Window, adopts the name of Smart Window, a side panel that can be activated at the user's discretion to receive contextual help while browsing.
This Smart Window offers features such as Automatic summaries of long articlesThis includes explanations of concepts, product comparisons, and one-off assistance with reading and analysis tasks. All of this is done without leaving the current page, saving time when working with extensive or highly technical content.
One aspect that Mozilla emphasizes is that these capabilities are completely Opt-inThey are not activated by default, require explicit user action, and are accompanied by a button to disable all AI from the browser all at once. This way, those who prefer a more traditional experience can continue using Firefox without any trace of these tools.
In some cases, access to Smart Window and certain experimental features is being managed through waitlists or via Firefox Labs, a space where early-stage features are tested. For the average user, this translates into the ability to experiment with the browser's AI without it becoming intrusive or permanent.
The strategy aims to differentiate Firefox at a time when almost all major browsers integrate some kind of smart assistant, but do not always provide such clear control over what is activated, what data is sent, and how those requests are managed.
Enhanced security and visual redesign: Firefox gets an update
In terms of security, Firefox 149 continues to expand upon the measures already implemented in recent versions. One of the most significant is the adoption of... Sanitizer API, a web standard designed to filter and clean potentially dangerous content before it can be exploited in XSS attacks and other common vulnerabilities.
By becoming the first browser to incorporate this APIMozilla attempts to anticipate some of the threats that affect the average user without requiring any changes. It's a silent layer of protection that helps reduce the risk of exploits through forms, text fields, and other interactive elements.
In parallel, Firefox 149 arrives accompanied by a visual facelift which the company internally calls Nova. This new design language introduces updated icons, refreshed themes, more rounded corners, smooth gradients on various interface surfaces, and a redesign of toolbars, menus, and the home page.
Among the changes that have been leaked, there is also talk of the possible Compact mode recoveryThis is something highly requested by those who prefer to concentrate more tabs and controls in the smallest possible space. In the medium term, Mozilla is also studying the integration of vertical tabs in line with this new aesthetic approach.
As a lighter detail, but one that reflects the attempt to refresh the browser's identity, it makes its appearance Kit, the new Firefox mascotwhich will gradually appear in different parts of the interface. It doesn't provide any functions in itself, but serves as a recognizable element in this phase of renewal.
With this entire package of changes, Firefox 149 stands out as a particularly significant update. The addition of a Free VPN built-inEven with a limited initial rollout and some open questions regarding audits and geographic expansion, Firefox reinforces the role of privacy as a central focus of the browser. At the same time, new productivity features, greater control over AI, and improvements in security and design position Firefox as a serious contender for those in Spain and Europe seeking a browser that better balances convenience, data protection, and flexibility for daily use.
