Mozilla has released Firefox 150 and Thunderbird 150, introducing refined split-view features, enhanced PDF management tools, and improved local data security for both browser and email users.

Key Points

• Firefox 150 adds a right-click option to open links in a new split-view pane and allows users to swap pane positions via the tab menu.
• The built-in PDF viewer now supports page manipulation, including reordering, removing, and exporting specific pages from documents.
• Thunderbird 150 introduces the ability to search within encrypted message bodies and includes a simplified Account Hub for easier configuration.
• Security updates include stricter network access restrictions for local devices and improved emoji support for macOS and Linux users.
• Both applications continue to offer Extended Support Releases (ESR), currently at version 140, for users requiring a more stable update cycle.

Why it Matters

These updates reinforce the importance of maintaining local, open-source alternatives to proprietary software for data sovereignty and reliability. By providing robust offline tools for email and web browsing, Mozilla offers a critical contingency for users who may face service outages or restricted cloud access.
