Farewell to Pocket, Hello Curated News

Following the discontinuation of the Pocket service in July, Firefox 142 introduces a curated news overview on the New Tab page. This feature organizes news by topic, allowing users to customize their experience by selecting or deselecting specific areas of interest. The rollout of this feature is gradual and may take a few days to reach all users 1

AI-Powered Link Previews

One of the most notable additions is the AI-driven link preview feature. Users can now right-click on a link to access a preview of the destination page's content. Optionally, a local AI can provide a summary of the linked page, offering users a quick understanding of the content without navigating away from their current page 1

Enhanced Profile Management and Interface Customization

The update also refines the vertical tabs feature introduced in Firefox 136. Users can now right-click on add-on icons in the sidebar to manage their visibility, providing greater control over the browser interface 2

Privacy and Security Enhancements

Mozilla continues to prioritize user privacy with Firefox 142. All AI features are implemented locally, ensuring that user data is not transmitted to external servers or cloud services. This approach sets Firefox apart from other major browsers that may collect user data for advertising purposes 2

The update also introduces an exceptions list for the strictest tracking protection. Users can now selectively disable tracking protection for specific websites where it may interfere with functionality, balancing privacy with usability 1
