You might want to try umatrix. there's a slight learning curve.

I set the defaults to load only the main site, and load no javascript. Then per-site I turn things on until it's workable.

basically start with:

  * * * block
  * * frame block
  * * script block
  * 1st-party * allow
  * 1st-party frame allow

then enable stuff for good sites.

that + reader mode makes even horrendous sites pleasant.
