JS Blocker

Version 5.3.2

Safari extension that controls which scripts run on websites.

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.

Can't install in Safari 10.1.1. Moving it into Safari's Extensions folder and starting Safari brings up a confirmation dialog for installing JSB 5.2.0, but it still doesn't install. Had to downgrade to 5.1.7 from Apple's Extensions Gallery

As Fyrejlye wrote already: Last installable Version was 5.1.4 There is NO WAY (and I tried ALL) to install the newer Versions. It's a pitty! I'm on OS X 10.12.3 and Safari 10.0.3 (12602.4.8) I rate my current Version 5.1.4 with 4,5 Stars

"Safari can’t install this extension. An error occurred, etc"
Also, no way to install it on Safari TP. Works only on Safari when you can install it.

I've found it impossible to install v5.1.5. I have v5.1.4 running successfully. But I've tried every which way to install v5.1.5 and Safari ALWAYS throws this error: "Safari can't install this extension An error occurred while installing the extension "JS Blocker 5". I'm using Safari v10.0.2 on macOS 10.12.2 Beta (16C53a) I've attempted to capture exactly what error is being thrown in the Console, so far without success.

No longer works for me in Safari 10.0 on OS X 10.11+.
Last working version was 5.1.1.
Latest version in Apple's Extension Gallery is 5.1.2.

I just spent an hour removing and installing multiple times. I thoroughly removed the extension and all traces in the Safari LocalStorage folder.
No matter what webpage I go to, the extension says "Did not receive a page from the active tab."
Well Ghostery did!

Developer rarely responds to emails - I only received one reply for NINE emails sent.

The Import function doesn't work so you can't save your settings.
Well, you can EXPORT them, but you can't IMPORT them.

This version (5.0.20.1) apparently fixes the Safari crashing bug in version 5.0.19. I'll keep my fingers crossed that it holds up. Except that it prevented the Post Review button on this page from working. So it's still problematical.

This version of JS Blocker (5.0.19) is a total disaster. It chokes Safari every time I try to install it. Because of that you cannot use Safari to uninstall it. The installer places files in two locations: There is a JS Blocker folder in ~/Library/Caches/com.apple.Safari/Extensions called JS Blocker 5.safariextension. Delete it. The JS Blocker 5.safariextension file is in ~/Library/Safari/Extensions. Delete it too and empty the trash. Then Safari should run properly again. By the way, I found these items easily using Find Any File. It's much easier to use than Spotlight and locates files Spotlight doesn't catalog, like hidden and system files. If you haven’t updated JS Blocker yet, don’t do it! And turn off Install updates automatically in the Updates section of the Safari Extensions preferences, if it’s currently on. Automatic updates may sound convenient, but with them turned on you will have a harder time figuring out what’s wrong with Safari when a problem like this occurs. The previous version of JS Blocker gave me problems, too, but reinstalling it solved them then. Now it’s a total bust. Don’t know what’s going on with the developer but it seems he’s now making malware. Grrrh! Even one beta tester should have found this problem before he released the update.

This version of JS Blocker (5.0.18) broke Safari. With it active I can no longer access bank and credit card sites that worked just fine a few days ago. Not having a copy of the earlier version handy, I was obliged to uninstall it.

It is good but it is waay too complicated. It would be great if it had a simple mode in the UI where one can just whitelist/blacklist the sites. I get only few sites with pop ups, I'd just like to black list them allowing all the rest. Even better with a confirmation dialogue box when an unlisted site tries to open a pop up.
