While uMatrix may be a bit of a pain, once you have your basic rulset and whitelists setup it functions very well, and beyond that, it really helps you understand what makes the modern web so shitty, and helps you know which sites are part of that and which aren't, which I think is pretty invaluable. Like many things, it may take more upfront investment but it's worth it imho.

If I could force every webdev to browse their site with a fresh uMatrix install I would.

I was most amused when he used my site as his test example in the uMatrix manual.
