Great on it's own, even better alongside Ublock. This addon has saved me from malicious popup windows and unrecognized ip connections more times than I can count. Plus, you can still have the Malware, scam and Pup shields active while having the ad blocker deactivated. So you can browse those pesky websites that force you to turn off ad blocker, but still be protected from actual threats when they appear. Great addon, 10/10.
