Oh :| I used CloudFlare it's free and https is enabled. i'll talk out @suasive.I'm talking about the Join User Group addon, not the Undelete one.
Also it looks like you're website is misconfigured to run the addon as it's attempting to request HTTP on a HTTPS website. You need to fix that for the overlay features to work properly.
Thanks for help me @silence!
