Mozilla has released a new Firefox roadmap that highlights upcoming features in productivity, privacy, performance, and AI.
The document was published with the Firefox 152 update. Some of the features listed have already been introduced, while others are being announced for the first time.
The release 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 reforms aimed at increasing productivity. It includes a redesign of the Nova interface, which was previously announced as a major update to the user interface.
Support for tab groups on mobile devices is also part of the plan. Mozilla is adding customizable keyboard shortcuts, saying this feature is the most requested by users.
Additionally, improvements have been made to PDF editing tools, allowing users to more easily split, merge, and reorganize files. A redesigned Settings page is already available in Firefox 152.
Mozilla is expanding its privacy features in Firefox to mobile devices:
- Built-in VPN will now be available on mobile platforms in addition to desktop. But
- For iOS, Firefox will receive basic ad and tracker blocking capabilities without the need for external add-ons.
This mobile VPN extension follows Mozilla’s existing promotional offer, which gives Firefox users unlimited VPN bandwidth and access to 28 countries until August 31.
AI features with user controls, plus performance and web standards improvements
Firefox is introducing optional AI features, including a “quick reply” tool that allows users to talk to a chatbot using voice commands.
Mozilla has highlighted that Firefox is using AI differently from other browsers, giving users control over AI-based capabilities. Those who prefer not to use 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 be a focus in upcoming releases.
What the Firefox Roadmap Means for Market Share References and Users
Despite active development efforts, Firefox continues to lose users. StatCounter reports that the browser’s desktop market share will fall 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 rollout of the Browser Choice screen under the Digital Markets Act, but the overall trend remains negative.
The roadmap shows that Mozilla is working on features that longtime Firefox users have been asking for, 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 users who prioritize privacy.
For those who are sticking with Firefox despite its declining market share, new features will be gradually released in the next few updates.
For users who have switched to a Chromium-based browser, the question is whether these upcoming features and Firefox’s continued stance against features like Manifest V3 will be enough to bring them back.
The Firefox Roadmap is openly published and available on Mozilla’s website. Although Mozilla has not set specific release dates for all the items, it has indicated that many will be rolled out in upcoming updates.
