Like I said, it's ridiculous how many powers extensions have. Browser developers should tackle this problem. For example, it shouldn't be possible for extensions to make outbound connections without a users permission and they should only be able to connect to a hard-coded IP address.
This extension monitors what other extension try to do. https://malwaretips.com/threads/extension-police.79576/post-714244
Interesting, but can we trust this extension, I'm guessing it also needs quite a lot of privileges, know what I mean?
Yeah, I understand. Which is why it's good that the developer replied on that thread. It helps to build trust between users and developers.
