Ever find yourself viewing a webpage when something annoyingly pops up, like an ad, or paywall, or a prompt to sign up for a newsletter? Or maybe you notice that even after the content has loaded, something is still using your network connection? Enter no.js, a tool that helps you effortlessly, and temporarily, disable Javascript for the page you're viewing. Easily prevent popups, tracking or analytics services, ads, and some paywalls. No need to go into your Safari settings and disable Javascript, only to immediately return to enable to. No need to strengthen content blockers, only to loosen them up again. Just two taps from any Safari view. ** No.js is NOT a content blocker. It is an extension that works in all apps that allow sending URLs to other apps. This means almost any app that has a way to view webpages, but actual mileage may vary. Also, some pages may appear broken when viewing them without Javascript, but good websites won't :)
Pro Script
Manually define custom rules for precise content blocking. This advanced utility offers granular control over scripts and web elements, enhancing your browsing experience alongside existing ad blockers.
- Custom script blocking
- Manual rule definition
- Advanced content control
- JSON rule editing
- Web browsing enhancement

Have you ever wanted to block a very specific script or scripts but your current ad blocker only deals in subscriptions or lists? If so this app is for you. Pro Script allows you to manually define your own custom rules for complete content blocking control. This is a pro-user level app offering the full power of content blocking at your fingertips. Use it along side your other ad blockers to enhance your web browsing experience. Again, this is a very advanced app meant for those who know what script or rule they need to add. This is not a general purpose ad-blocker. If you're really feeling powerful you can edit the raw JSON for the blocker. It will be ran through a validator just in case the syntax is off just a bit.
