Most tech people now seem to use uBlock Origin. But I use uMatrix (from the same developer) and I am super happy with it. It took me a minute or so to understand the interface. But then it is super intuitive and exactly the way I would have designed it myself. Since I only allow the hosts that I need, I almost never see advertising. And the web is blazingly fast.
Has it got an easy way to unblock elements? Going through the every request in the logger using uBlock is pretty tedious.
I actually just switched from uMatrix back to uBlock Origin, because uBlock makes it easier to block individual JavaScript files, rather than blocking JS wholesale.
