Hello, I'd like to learn how to deal with the uMatrix add-on, made for privacy concerned users. It blocks all of browser's requests by default, then you are expected to manually select every and each request that the browser should make to servers.

the add-on displays a modal dialog by the side of the main browser document, which I was able to find with NVDA, but then it displays a list of suposed requests it blocked, which I was unable to discover how to enable/disable. If anyone is willing to try it and give some feedback, I'd be grateful.
