Message Thread Cleaner

Message Thread Cleaner helps you remove chat threads from your own Facebook Messenger inbox in a controlled, transparent way. Each run starts with the first visible conversation and continues in the inbox order shown by Messenger. Choose a limit of 10, 25, or 50 chats per run, or deliberately select no limit. Before a run can start, you must acknowledge that Messenger chat deletion is permanent. You can stop the process at any time from the extension popup. Key features: - Runs only on Facebook Messenger pages - Requires an explicit start for every run - Offers clear per-run deletion limits - Provides live progress and stop controls - Processes the page locally in your browser - Does not collect, store, sell, or transmit personal data - Contains no advertising, analytics, or remote code Important: Deleting a Messenger chat is permanent and cannot be undone. The extension depends on Messenger's current page controls, which Meta may change without notice. Message Thread Cleaner is an independent extension and is not affiliated with, endorsed by, or sponsored by Meta Platforms, Inc.
