Very handy! Needs an easier way to analyze websites to add to whitelist. As it stands the homepage https://searxes.danwin1210.me/ is blocked.

Needs to allow over-writing "Always allow" settings manually.
The GUI:
Needs to implement wildcard usages for both sites and specific requests(enable any third party requests from this site and enable this third party request on any site).
Should have a "block blacklisted only" mode

I said the GUI because in the Add-ons Manager it implies there actually is a wildcard *

Not bad, but honestly if you use the internet like any normal person it's more of a bother than anything else, 20 blocked requests on facebook and counting, any site you watch videos from usually loads it from some other place... you have to exclude it, etc...
I turned on the always allow settings and it literally always allows things, even if I set it to not allow certain things they don't get added into the blacklist.
