Mozilla Firefox is one of the longest-running web browsers, first released in 2004 as an alternative to Internet Explorer, rest in peace. Over the years, Firefox has carved out a sizeable install base, with more than 200 million monthly active users drawn to its speed, deep customisation options, and privacy-focused approach.
Earlier this month, in December 2025, Mozilla appointed a new CEO amid ongoing financial pressure. Unfortunately for long-time fans of the browser, that leadership change comes with a strong push toward AI. Still, there may be a saving grace on the horizon, raising the question of whether Firefox can adapt without losing its identity, or if it is finally time for some users to look elsewhere.
Firefox as an AI browser
It seems like nobody can escape the pull of AI lately, and Mozilla Firefox is no exception. New CEO Anthony Enzor-DeMeo has outlined plans to evolve Firefox into what he describes as a modern AI browser, a direction that has alarmed many users and raised questions about whether it is time to look for an alternative that avoids AI altogether.
Fortunately, at least for now, Mozilla has confirmed that users will be able to disable all AI features within Firefox if they choose. This means AI functionality will be opt-in, rather than something forced on users by default.
That already puts Firefox in a better position than competitors like Microsoft Edge and Google Chrome, neither of which offers a clear, one-click way to disable AI features across the browser fully.
For the time being, Mozilla appears committed to user choice, and being a trusted software company, with the new CEO stating:
As Mozilla moves forward, we will focus on becoming the trusted software company. This is not a slogan. It is a direction that guides how we build and how we grow.

Mozilla is dubbing the opt-out of AI features an AI kill-switch internally, giving users a straightforward way to disable any and all AI features within Firefox, with the Firefox Web Developer account on Mastodon stating:
Something that hasn’t been made clear: Firefox will have an option to completely disable all AI features.
We’ve been calling it the AI kill switch internally. I’m sure it’ll ship with a less murderous name, but that’s how seriously and absolutely we’re taking this.Firefox Web Developers.
The bigger question is whether this will be enough for you, or if you have already decided to move elsewhere and adopt a different browser.
