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.
This is the only tool you need. It works in Chrome, Firefox, Safari, Edge and Opera.
Get Cookie-Editor (free)Opens cookie-editor.com, which sends you to the right add-on store for your browser. It's a well-known, reputable extension.
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 Cookie-Editor icon in your toolbar. If you don't see it, click the puzzle-piece menu and pick Cookie-Editor from the list.
In the little window that opens, click Export (bottom toolbar), then choose Export as JSON. 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.
