This add-on uses about 1/2 GB of Memory in Firefox. It claims to be easy on CPU and Memory? I need to look for lighter ad blockers!

Absolutely brilliant, essential add-on. Greater than the power of ABP and NoScript combined while using less system resources to boot! If you learn how to block/allow scripts with this, it's your one stop shop for privacy + security. My only issue is that, from a novice's perspective it's not clear what "I am an advanced user" does from looking at the preferences page. Maybe have a bold heading that reads "Script blocking" or something then the checkbox could say "Enable (for advanced users only)". A major philosophical difference from NoScript in that "advanced user mode" is essentially saying "enable only if you know what you're doing" vs "not blocking scripts is dangerous! Do it! Figure it out from there" kind of thing I guess.
