Mozilla has released a new Firefox roadmap that highlights upcoming features in productivity, privacy, performance, and artificial intelligence.
The document was released alongside the Firefox 152 update. Some of the features listed have already been introduced, while others are announced for the first time.
The launch coincides with a decline in Firefox’s desktop market share, which fell from 5.88% in May 2025 to 3.79% in May 2026, according to Statcounter.
Productivity updates and new privacy and security additions to Firefox
The roadmap highlights several improvements aimed at boosting productivity. It includes a redesign of the Nova interface, which was previously announced as a major UI update.
Support for tab groups on mobile devices is also part of the plan. Mozilla is adding customizable keyboard shortcuts, a feature they say is among the most requested by users.
Additionally, there are improvements to PDF editing tools, allowing users to split, merge, and reorder files more easily. A redesigned Settings page is now available in Firefox 152.
Mozilla is expanding its privacy features in Firefox to mobile devices:
- The built-in VPN will now be available on mobile platforms in addition to desktop. In
- iOS, Firefox will receive basic ad and tracker blocking capabilities without the need for external plugins.
This mobile VPN expansion comes after Mozilla’s current promotional offer, which is offering Firefox users with unlimited VPN bandwidth and access to 28 countries until August 31.
AI features with user control, plus performance improvements and web standards
Firefox is introducing optional AI features, including a “Quick Replies” tool that allows users to talk to chatbots using voice commands.
Mozilla has highlighted that Firefox approaches AI differently than other browsers, giving users control over LLM-based capabilities. Those who prefer not to use the AI features can choose to disable them.
Firefox 152 adds experimental support for the JPEG XL image format. HDR video support is also coming to Windows and Linux systems, fulfilling a request that has been open for more than six years on Mozilla’s bug tracker.
Support for web APIs and built-in security protections will continue to be a focus in future releases.
Market share context and what the Firefox roadmap means for users
Despite active development efforts, Firefox continues to lose users. Statcounter reports that desktop browser market share fell from 5.88% in May 2025 to 3.79% in May 2026. The decline has been steady, with Chrome remaining dominant and Edge gaining ground.
Mozilla recently announced an increase of six million users in EU markets following the implementation of browser choice screens under the Digital Markets Act, but the overall trend remains negative.
The roadmap shows that Mozilla is working on features that long-time Firefox users have requested, including HDR support, customizable shortcuts, and better tab management.
Extending the built-in VPN to mobile devices and adding ad blocking on iOS may appeal to privacy-first users.
For those who have stuck with Firefox despite its dwindling market share, new features will be released gradually over the next few updates.
For users who have switched to Chromium-based browsers, the question is whether these upcoming features and Firefox’s continued stance against features like Manifest V3 will be enough to get them back.
The Firefox roadmap is openly published and available on the Mozilla website. While Mozilla has not set specific release dates for all items, it has indicated that several will be implemented in future updates.
