>> We found that more than 71% of extensions require permission to “read and change all your data on the websites you visit”.
This is exactly the reason why I install so few extensions and buy none.
The same is becoming true for Android Apps, more of them require more permissions every day. Recently an app I'd run for months if not years wanted to install an update and demanded that I give it permission to view my phone calls and even the remote caller's phone number. This had nothing to do with the purpose of that app, all it would need at most is to know if a phone call came in so it could pause.
Do you mean if I open tab A on one site and tab B on another then they can read each other's data without any special permissions from me? If so then that's a security breach and not a discussion of which permissions a web app or mobile app should be allowed to have.
