NoSpy ‑ Anti Fraud Spy Blocker

The best extension on blocking thieves, believe me, I tried every single other extension and none of them got even close, and by far the only spy app that has one of the best support ever, Reda helped me with all my requests even added new features in the app, only by me asking him, I'm extremely pleased with the app and the support those guys offer. 10/10 I really recommend you install it, you won't be disappointed.
