JS Blocker overview

JS Blocker is a Safari extension that protects your privacy and keeps you safe on the web by blocking scripts and others from tracking you-similar to NoScript for Firefox.

Features
  • Quickly and easily block advertisers, tracking agencies, and social media networks from monitoring your online activity.
  • Prevent websites from figuring out where you came from.
  • Prevent all scripts on the webpage from being allowed to run.
  • Block frames, AJAX requests, embeds, objects, videos, and hide images.
  • Block many JavaScript annoyances such as alert dialogs getting in the way, forms not autocompleting, windows being resized, and more.
  • Inject user scripts into webpages for even greater control with full Greasemonkey API support.

DISCONTINUED. Safari 12.0 radically changed its extension system. Apple's goal was to increase Safari security. Unfortunately, not all of Apple's choices in blocked extensions made sense. JS Blocker is IMHO the most unfortunate casualty. It no longer works with Safari and will not be updated to fit into Apple's requirements. JS Blocker was brilliant, incredibly useful and relatively easy to use. I will miss it. If Apple does in the future allow for extensions like JS Blocker, I will be very grateful. I wrote to Travis Roman, the developer. Here is his reply: "Apple has dropped support for what they deem "legacy extensions". JSB will never work again going forward unless Apple reverses this decision. Sorry about this, but there's nothing I can do...." BTW: If Safari give you a popup warning saying "Safari can't install this extension. An error occurred while installing the extension "JS Blocker 5".", what's going on is Safari attempting to inexplicably install the remaining version of JS Blocker in the now legacy Safari extensions Gallery. Apparently, Apple hasn't yet cleaned out its Gallery of blocked extensions. The old Gallery is being deprecated in favor of the a App Store equivalent anyway. To stop this inexplicable popup warning, uninstall JS Blocker from your extensions.

Version 5.2.2 has been available at the developer's site for some time now. I've also had trouble updating JS Blocker. The solution that works for me is to uninstall it from Safari/Preferences/Extensions and then double-click on the newer .safarextz file. I just did this five minutes ago and it worked. I'm using Safari 10.1.1 in El Capitan. Also, JS Blocker is donation-ware. There is no fixed price but major features are disabled until you make a donation.
