Firefox 151 new features update has officially rolled out, bringing several new tools and improvements for desktop and mobile users, including VPN location selection, expanded AI controls, and a one-click private browsing reset feature.
Mozilla says the latest release focuses on improving privacy, convenience, and user customization across devices.
Firefox 151 Adds VPN Location Selection
One of the biggest additions in the Firefox 151 new features update is expanded control over Mozilla’s built-in VPN service.
Users can now manually choose browsing locations across several supported countries.

Supported VPN Locations
Firefox users can currently select VPN routing through:
- United States
- United Kingdom
- France
- Germany
- Canada
Mozilla says additional regions will be introduced in future updates.
How the VPN Feature Works
By default, Firefox automatically recommends the closest available VPN location for better performance.
However, users can switch locations manually whenever they choose through browser settings.
Mozilla also noted that local content restrictions and regional laws still apply depending on the selected location.
Mozilla Reports Strong VPN Adoption
Mozilla revealed that more than one million users have signed up for Firefox’s free VPN service since its launch roughly two months ago.
The feature has become one of the most discussed additions in the Firefox 151 new features update due to growing interest in browser-based privacy tools.
Expanded AI Controls Arrive on Mobile Devices
Firefox 151 also expands AI-powered features to iOS and Android devices after previously introducing them on desktop versions earlier this year.
AI Features Available on Mobile
Depending on device and region, users can access:
- AI-powered webpage summaries
- Voice search functionality
- Translation tools
- Smart browsing assistance
Users can manage these tools directly through Firefox settings.
Shake to Summarize Feature Expands
Mozilla’s “Shake to Summarize” feature is now available on Android in English.
The tool allows users to shake their phone to generate a quick AI summary of a webpage.
On iOS, the feature supports multiple languages including:
- English
- German
- French
- Spanish
- Portuguese
- Italian
- Japanese
This feature is one of the standout additions in the Firefox 151 new features update.

New One-Click Private Browsing Reset
Mozilla has also introduced a new privacy-focused tool for Private Browsing sessions.
Flame Button Clears Private Sessions Instantly
A new flame-shaped icon now appears beside the address bar in Private Browsing mode.
Clicking the button instantly:
- Clears cookies
- Removes browsing history
- Deletes session data
- Resets login activity
The browser then immediately starts a fresh private session without requiring users to close the browser window.
Firefox Nightly Testing Redesigned Settings Page
Mozilla is also testing a redesigned settings interface in Firefox Nightly builds.
Upcoming Settings Improvements
The redesigned page includes:
- Cleaner navigation layout
- Better organization of settings
- Improved labels and categories
- Built-in search functionality for settings
Mozilla says the redesign will first launch for Nightly users before expanding more widely.
