Ok

This is the best extension I've tested so far!
Works as expected, and blocks EVERYTHING
you tell it to block! I recommend it to everyone!

I use this in my private life *extensively* here I'll be trying to ensure that I can apply a tool like this to work seamlessly in a work context without too much overhead in times of being a time-sink.

I've been using this for years to block JavaScript from random third-party sites. It can be a bit tedious at times to enable enough sites to make things work, but well worth the effort to improve long-term performance and possibly security.
