I use several add-ons in firefox, and largely they feel trustworthy, but I dont have any means for limiting the scope of what they are able to do, the manifest tells me what they can do and thats it. I have read through this page https://support.mozilla.org/en-US/kb/permission-request-messages-firefox-extensions, but I have had a hard time even understanding which permissions let an add-on make network requests. Barring the ability to actually stop add-ons from making network requests is there any visibility into what requests are being made by an extension, or all extensions in the browser?
