To read listings inside private groups, Housing Scout needs to view Facebook as you — a logged-in member. You give it permission by copying your Facebook "session cookies" once. It takes about two minutes, and you'll only redo it every few weeks.
Works in Chrome, Edge, Opera, Brave and other Chromium-based browsers. Not available for Firefox or Safari.
Get EditThisCookie (V3) — freeOpens the Chrome Web Store listing. It's a well-known, actively maintained extension with ~400K users.
Go to facebook.com in the same browser and sign in as normal. Leave that tab open.
While you're on the Facebook tab, click the EditThisCookie icon in your toolbar. If you don't see it, click the puzzle-piece menu and pick EditThisCookie from the list.
In the little window that opens, click the Export icon (bottom toolbar), then choose JSON as the format. That copies all your Facebook cookies to your clipboard — nothing gets saved to a file.
Come back here, paste into the Facebook session cookies box (replace anything already there), and click Save settings. That's it — you're connected.
