Mozilla announced Firefox Enterprise on 12 October 2026, a version of its Firefox browser for organisations that want tight control over security and data. The first release, Firefox Enterprise 158, was made available on 13 October, according to Mozilla’s release notes.
What it is
In its announcement, Mozilla says Firefox Enterprise “is built for organizations with strict security, governance, and compliance requirements. It pairs the Firefox browser, built on Mozilla’s independent Gecko engine, with a management console organizations can run on their own infrastructure.”
From that console, Mozilla says, IT teams can “centrally manage browser policy and access, govern how data moves through the browser and set controls around AI use.”
The key difference from rival business browsers is where the management happens. The release notes say organisations run the admin console and its supporting services, including updates, telemetry and crash reports, on their own servers. Security logs go “to your organization’s admin console, not to Mozilla.”
Mozilla says the product is designed to fit alongside tools companies already use: “Keep your identity provider. Keep your SIEM. Keep your MDM.” Those are, respectively, the system that handles staff log-ins, security monitoring software, and software for managing company devices.
What it can do
According to the release notes, features include:
- Company sign-in: staff must log in through their organisation’s single sign-on before browsing.
- Device checks: admins can require that a device meets security standards, such as having disk encryption turned on, before anyone can sign in.
- Data loss prevention: admins can block or warn about pasting, uploading, downloading and printing on chosen websites. Mozilla’s example is blocking pasting into AI tools the company has not approved.
- Watermarking: sensitive pages can be stamped with details such as the employee’s email address, to discourage screenshots.
- Lockdown Mode: extra restrictions for risky or sensitive websites.
- Encrypted profiles: browsing history and saved logins are encrypted on disk, with the key held by the company’s console.
- Access without a VPN: staff can reach internal company sites from personal devices through a connector the company runs.
Why Mozilla is pitching independence
Mozilla is framing the launch around “digital sovereignty”, the push, especially in Europe, for organisations and governments to depend less on a handful of big technology providers. Mozilla says Gecko is “the only major browser engine developed outside Google and Apple.”
“If all your options are built with the same technology underneath, ‘choice’ is a lie. So is control,” said Anthony Enzor-DeMeo, Mozilla’s chief executive.
Mozilla says Firefox “is used by roughly 200 million people every month and is already deployed across thousands of organizations.”
Where and how it is sold
Firefox Enterprise is not launching worldwide yet. Mozilla says it is “unveiling across Europe with an initial sales focus on France, Germany, Austria and Switzerland, with more markets to follow.” The release notes say organisations can request early access.
Mozilla has not published a price. Computerworld reported that Mozilla will use a subscription model “that doesn’t depend on monetizing customer data or forcing a roadmap,” and that Firefox Enterprise includes Mozilla’s paid Firefox Professional support.
Mozilla also says a Thunderbird Enterprise version of its email software “is also in development”. It has not been released.
What this means
- Mozilla is entering the business browser market, competing with enterprise versions of Chrome and Edge and with security-focused browsers.
- Self-hosting is the selling point. Organisations run the management system themselves, so browser data and logs stay in-house.
- It starts small. Sales begin in four European countries, with no public price yet.
