Is Multigroup Poster – Facebook Group Auto Poster, Bulk Post & Scheduler safe?

Clean risk

Multigroup Poster adds account email, ID, and name to its uninstall feedback URL.

When the extension sets its uninstall feedback page, it reads the stored user account record and appends the email address, user ID, and name as URL query parameters. It also rewrites the Origin header to facebook.com for credentialed Facebook API and upload POST requests made from the extension context.
