Mozilla has updated Firefox with a new feature that lets users combine PDF files directly in the browser without relying on external websites. The capability arrived in the Firefox 151 release and keeps all processing on the user's device.
Firefox's PDF viewer already supported annotations, form filling, drawing, image insertion and digital signatures. The latest addition allows merging multiple documents while preserving privacy by avoiding uploads to third-party servers.
Mozilla has made its Smart Window AI browsing mode available in limited beta to Firefox users in the United States and Canada. The feature adds an integrated assistant that can access tabs, history and current pages.
