Is this available as pastable text, ideally with the explanation parts as comment blocks?

Happy to see you recommend uBlock Origin and LocalCDN. I would humbly suggest ClearURLs might belong. Another excellent "set it and forget it" extension that skips common tracking redirects.

Funny that you mention ClearURLs.

I was actually reading its codebase and wasn't happy with it due to potential sanitization problems with its regex usage and other things. So I kind of wrote it from scratch and it got to be something different.

But as always with my projects, nothing is ever really finished or usable.
