That's the same extension installed by Firefox when you enable Studies. The extension is signed by Mozilla. On Android, I can see the extension in "Addons" with a button to uninstall it. The desktop version hides it and doesn't have the option to uninstall. We have Studies disabled on OpenBSD because Mozilla did a bad use of the feature in the past. Search "firefox studies mrrobot". With Studies enabled, they can change anything in your browser remotely without notifying you. -- Juan Francisco Cantero Hurtado http://juanfra.info
