fb_scr_izan collector

A browser extension that collects Facebook group posts from your own logged-in session, then lets you search and export them. Everything stays in your browser — nothing to install but the extension.

Install

  1. Unzip the download.
  2. Open chrome://extensions and turn on Developer mode.
  3. Click Load unpacked and choose the unzipped folder.

That is the whole installation. Nothing else to install, nothing to run, no server and no terminal. The extension stores what it collects in your own browser.

Use

  1. Open a Facebook group you already have access to, in a new tab. A tab that was already open when you installed the extension will not collect until you reload it.
  2. Click the extension icon and press Start Collection.
  3. Scroll the feed yourself. The popup counts new posts and duplicates as they arrive.
  4. Press Stop when you are done.
  5. Click View Results to read, search and export everything collected, as CSV or JSON.

Optional: the self-hosted workspace

Most people never need this. If you want collections from several machines in one database, with cross-group analysis, you can run the workspace yourself from the project repository and point the extension at it under Extension settings. Sending to a workspace is off by default.

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.
