You can actually setup ublock0 to do this for you too. At one point I'd used it to blur distracting sites, but like you, I found fully blocking the content(which the blurring effectively did) led to me disabling the block. I'll try this technique out, it's a good idea.

Here's how you can do it with ublock:

  www.reddit.com##img:style(filter: blur(10px);)
  www.reddit.com##body:style(filter: grayscale(1);)

ublock seems to be able to do anything :P

That's good, but I still much prefer a simple toggle, and I'd like to expand it with more complex features as well.
