Mozilla is preparing a radical refresh of Firefox with Project Nova , a new design that will make privacy settings easier to access and offer clear controls for artificial intelligence features . The refresh is expected to launch later this year and promises to bring back the popular compact mode along with more customization options. The strategic move comes at a critical time when users are looking for alternatives to mainstream browsers that aggressively integrate AI features without explicit consent.
Project Nova introduces a completely new visual design with rounded interface elements throughout the browser. Tabs will now be shaped like bubbles, while the new color palette is inspired by fire, Firefox. Mozilla also announced that it is updating all icons to be visually consistent across both light and dark themes. This aesthetic change aims to make Firefox more appealing to newer users, while maintaining familiarity for long-time users who value functionality over looks.

One of the most important features of Project Nova is the redesigned Settings section , which will make it much easier to find and use privacy settings. Of particular note is the new toggle that allows users to disable all current and future AI features with a single click . This approach represents a clear differentiation from other browsers that integrate artificial intelligence as a default feature. At the same time, this feature is gaining particular importance as concerns about data protection and transparency of AI algorithms used by big tech companies grow.
New features and improvements in Firefox Project Nova
Alongside the upcoming visual refresh, Mozilla announced new features that are already available. Support for the Web Serial API now allows websites to control devices or deliver firmware without requiring native apps or installers. This new feature is part of Firefox 151, which was released this week and also includes an updated design for the Firefox home page, new wallpapers, and the ability to merge multiple PDF files via the built-in viewer.
The return of compact mode is a major win for power users who prefer more “compact interfaces.” This feature squeezes browser controls, such as the forward and back buttons, saving valuable screen space. In addition, the new design will make it easier to access features such as tab groups, vertical tab view, and split view. These functionality improvements prove that Mozilla is listening to community feedback and trying to balance modern design with practical usability.
In terms of customization, Project Nova will offer new wallpapers and color themes that will be applied to the entire browser window. The new themes will feature both light and dark versions, similar to Google Chrome. Mozilla also says it's exploring controls for the shape of tabs and other interface elements, which could offer unprecedented levels of personalization in the browser space.

When it comes to AI features, Firefox’s approach differs significantly from the competition. AI models and features are not downloaded to a user’s computer unless they explicitly choose to use them. This contrasts with Google Chrome, which can download up to 4GB of data for AI features without explicitly notifying the user. Additionally, when users choose to install AI, Firefox provides clear information about how much space they take up and exactly which ones are installed.
Practical tips for getting the most out of the new Firefox
To fully utilize the new features of Project Nova, users should familiarize themselves with the updated privacy settings. It is recommended that they visit the Settings section once the update is available and explore the new AI control options. Users interested in maximum privacy protection should enable full AI and review the telemetry settings.
Mozilla’s strategy with Project Nova reflects a broader effort to maintain Firefox ’s reputation as a browser that prioritizes privacy and user choice . In an era where most competitors are aggressively integrating AI features , Mozilla is choosing to offer transparency and control . This approach could prove critical to maintaining and expanding Firefox’s user base, particularly among users concerned with protecting their privacy.

The update comes at a critical time for Firefox, as its market share remains in the low single digits worldwide, while Chrome dominates with about two-thirds of global usage. Project Nova represents a significant investment by Mozilla in the future of Firefox, aiming to provide a real alternative for users looking for a more transparent and controlled way to browse the web.
According to The Verge, Project Nova is expected to launch later this year, offering users a more modern and customizable browsing experience without sacrificing the privacy principles that characterize Firefox.
