### 5/5 — Unique

*2025-07-12, version 2.0.3*

Easily allows whitelisting JavaScript, cookies, fonts, etc. on a per-site basis from within Safari. Sheriff is unique in this regard. Most other content blockers focus on an ad-blocking workflow or similar. Which is still beneficial, but tackles a different issue. 

Would love to see this available for macOS. Having strict control over JavaScript, cookies, and fonts is a must for me. 

I think this could become hugely popular with technical users if it was easier to discover. Searching “Sheriff” brings up lots of unrelated stuff.

### 5/5 — Awesomeness.

*2025-06-22, version 2.0.3*

Greatness in this app.

### 5/5 — Finally

*2025-06-18, version 2.0.3*

I've been looking for a content blocker like this off and on for years. My only gripe is it's not available for MacOS

### 1/5 — Good app

*2025-04-09, version 2.0.3*

Biggest downside is ex boyfriends and hackers use it to stalk you and get away with with. Going to police station and phone store on the 11th. No one’s privacy should be this easy to invade and control

### 5/5 — Unique Outstanding Design App!

*2025-02-09, version 2.0.3*

Security never thought this word would become so important in my old age. I know walking around with my cane Security is important as to the path I take or the area I choose. But I never thought walking on the internet would also become a factor. Where crooks who invented the words Scam and Fraudulent and Triggering all kinds of ways to steal you myself and our Family Money and of course our identity if given the opportunity. Thanks to this great Developer He has created a Unique Outstanding Design App to protect all of us. The Developer has put in a great deal of Work Time Sweat and yes Love into the coding of this Software. How do I as an ole man know look at the number of updates that has been made and the fact that this Unique Design App really does work! I at first being an ole man trying to learn new Technology turned on everything you could block! ( boy was that a mistake ) when I when for my walk on the internet suddenly nothing opened up I was over Blocking. Scratching my head with what Hair I had left I knew I had done something wrong. But I knew I had to start over and block what I knew and look up what I didn’t understand before I chose to block that. With this method for me it worked and I am blocking what is good for me the ole man and I didn’t go gung-ho the second time around. If you have taken the time to read this download the software give it a try the price is not really bad. So anyway Mr Developer I would like to truly Thank you for this Unique Outstanding Design App and I truly truly Tip my Hat 🎩 to you and Say “ Thanks “ yup it’s really a 5 Star ⭐️.

JavaScript blocking, cookie blocking, custom rules and subdomain permissions. It doesn’t stop there! It blocks web sockets, fetches, pings (FU HACKERS)  popups, media, SVG documents, fonts, stylesheets, images and documents. No more URL injection schemes and crafted URLs will be inflicting system changes on my machine.
