Install

  1. Unzip the download.
  2. Open chrome://extensions and turn on Developer mode.
  3. Click Load unpacked and choose the unzipped folder.
  4. Start the workspace:
    python run_server.py
    Then open http://127.0.0.1:5001 and sign in.
  5. In the workspace, open Group Posts and click Connect Collector. The extension pairs itself — there is no token to copy, and none is shown on screen.
  6. Open a Facebook group in a new tab. A tab that was already open when you installed the extension will not be collected from until you reload it.

Use

  1. Open a Facebook group you already have access to.
  2. Open the extension popup and press Start Collection.
  3. Scroll the feed yourself. The popup counts new posts and duplicates as they arrive.
  4. The same counters appear in the workspace, which is where the posts are stored.
  5. Press Stop when you are done, then browse and export under Results.

Why you scroll manually

Programmatic scrolling does not reliably make Facebook load more posts. Measured on a live group feed:

MethodResult
Real wheel events height 5330 → 12762, posts 3 → 4 paginates
scrollTop = max no change, no new requests no effect
scrollBy ×12 height +7px no effect

An extension cannot dispatch trusted wheel events, so the collector works passively while you scroll rather than pretending to automate it. Its assisted-scroll mode measures whether posts actually arrived and stops when they did not.
