Can I deny an addon certain permissions listed as “required”?
-
Can I deny it to phone home, as in block any custom outbound connection it tries to establish?
More toggle switches for things like that would be nice compared to “The developer says this extension doesn’t require data collection”
I think you should be able to edit
permissionsin the extension’smanifest.json. I don’t know if they will be overwritten by updates though. I was working on an experimental local add-on, so I had more control over it.See: https://developer.mozilla.org/en-US/docs/Mozilla/Add-ons/WebExtensions/manifest.json
