I have checked multiple times and gorhill doesn't appear to accept donations. I seem to recall reading a thread where they indicated they didn't want to ever be considered to be beholden to anyone.
As mentioned above, uMatrix is my favorite. Once configured, it is easy... There is a learning curve.
I'd donate regularly, but that doesn't appear likely. I greatly appreciate their work.

I think /u/gorhill is the lord of this particular war, and his followers are armed to the teeth. I type this on Firefox on Android with uBlock Origin.
I check his github occasionally to see if he accepts donations, and I donate to a couple of the lists occasionally.
In the war analogy, we have the best arms dealers. They other side is fighting a losing war.
