Share Backported is a Firefox extension designed to reinstate the share feature that was removed in Firefox Nightly 57. This user-friendly tool opens a modal window within the Firefox toolbar, allowing seamless sharing across numerous social networks and communication platforms such as Twitter, LinkedIn, Reddit, and WhatsApp. With its extensive compatibility, users can easily share content to services like GMail, Telegram, and Pinterest, among others, enhancing their social networking experience significantly.

The extension also supports the Container feature and integrates with the Facebook Container extension, ensuring that users can manage their privacy effectively. Share Backported requires specific permissions for the Container support, which is essential for its functionality. Ideal for users who frequently engage with multiple social media platforms, this free extension streamlines the sharing process, making it a valuable addition to the Firefox browser.
