Firefox 143 adds Microsoft Copilot AI and Google Lens support
The latest version of Mozilla Firefox, 143, has rolled out exciting new features that enhance user experience and security. With the integration of cutting-edge AI tools and improved functionalities, Firefox is continuing to evolve as a competitive browser in a saturated market. This update not only brings familiar tools from other browsers but also introduces innovative features that will enhance how users interact with the web.
As technology progresses, browsers must adapt to meet user expectations for speed, security, and convenience. Let's dive into the key updates and security enhancements in Firefox 143.
New features introduced in Firefox 143
Firefox 143 presents a multitude of new features that are set to improve user experience significantly. Among the most noteworthy additions is the inclusion of Microsoft Copilot in the browser's sidebar, enhancing the options available for AI-assisted browsing.
In addition to Copilot, Firefox has also integrated Google Lens, a feature that allows users to search for information directly from images. However, it's important to note that this functionality requires Google to be set as the default search engine and is being rolled out gradually.
To enable Google Lens for reverse image searches, users can follow these steps:
- Type
about:configin the Firefox address bar. - Search for the
browser.search.visualSearch.featureGateflag. - If the flag is set to “false,” double-click it to change it to “true.”
- The change should take effect immediately.
Another standout feature in this update is the ability to run websites as web apps that can be pinned directly to the Windows taskbar. This feature is accessible via a new pin icon located on the right-hand side of the address bar. However, users should be aware that this functionality is not available for Firefox installations from the Microsoft Store. Future updates are expected to bring similar features for Linux and macOS users.
Additional improvements include:
- The capacity to pin tabs by dragging them to a designated area at the top of the tab bar.
- A camera preview that appears when websites request camera access.
- Display of important dates and events in the address bar, enhancing user engagement.
For users requiring accessibility applications, Firefox has introduced the option to utilize Microsoft UI Automation. This allows tools like Windows Voice Access and Narrator to interact seamlessly with the Firefox interface. Mozilla plans to gradually roll out this feature over the coming weeks.
Security enhancements in Firefox 143
With every update, security remains a top priority for Mozilla. The release of Firefox 143 addresses numerous vulnerabilities that could affect user safety. Mozilla’s Security Advisory 2025-73 outlines at least 11 vulnerabilities that have been addressed in this version.
Among these vulnerabilities, two have been categorized as high risk:
These vulnerabilities pertain to the Canvas2D graphics component, which could allow malicious code to escape the browser's sandbox environment. Furthermore, other vulnerabilities are categorized as medium or low risk. Notably, one entry details a series of memory safety bugs discovered internally, summarized under the identifier CVE-2025-10537, which is also classified as high risk.
Comparing Firefox 143 with other browsers
As Firefox enhances its feature set, it's crucial to compare it with other leading browsers like Chrome, Edge, and Safari. Here are some key points of comparison:
| Feature | Firefox 143 | Chrome | Edge |
|---|---|---|---|
| AI Integration | Microsoft Copilot | N/A | AI features through Bing |
| Google Lens Support | Yes (Gradual Rollout) | Yes | Similar Functionality |
| Tab Management | Pinning by Dragging | Fixed Tab Pinning | Similar Features |

This comparison illustrates how Firefox is working to keep pace with and even surpass other major browsers in offering innovative features while maintaining a focus on user security.
