Lee-Su-Threads is a Firefox extension designed to enhance social media interactions by automatically fetching and displaying location information from posts. This tool enriches user engagement by showing the author's location right next to their post timestamps, providing context to the shared content. It features a caching mechanism that retains the fetched data for up to 72 hours, ensuring users have quick access to relevant information without unnecessary delays.

In addition to its core functionality, Lee-Su-Threads includes data export capabilities, allowing users to export all collected information in JSON format. To maintain a smooth user experience, the extension incorporates rate limit protection, automatically pausing when Threads imposes restrictions and alerting new users with a notification if they registered within the last two months. This helps ensure that users can navigate their social feeds efficiently and effectively.
