The company was immediatelly attacked for trying to "kill ad blockers," and after months of criticism, Google eventually backed down on its initial plan and settled on a higher limit ranging from 90,000 to 120,000, a number that many extension developers, and especially those managing ad blockers, still consider insufficient. Google wanted to limit the maximum rules an extension could pass to Chrome to 30,000, which many Chrome extension developers said was extremely low, and wouldn't even begin to accommodate the likes of ad blockers, parental control or traffic inspection extensions. Instead, the extension will deploy a set of "content blocking rules" and the browser will do the blocking without the extension seeing any user data. They will limit how extensions intercept and block web requests by preventing the extension from interacting with the web request directly. Grrrh! Even one beta tester should have found this problem before he released the update.In a very simple explanation, the changes that Apple implemented in Safari and the upcoming changes planned for Chrome have taken the same path to the same goal, but with different code and terminology.īoth Chrome and Safari will use a new extensions backend. Don’t know what’s going on with the developer but it seems he’s now making malware. The previous version of JS Blocker gave me problems, too, but reinstalling it solved them then. 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. 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. It's much easier to use than Spotlight and locates files Spotlight doesn't catalog, like hidden and system files. By the way, I found these items easily using Find Any File. The JS Blocker 5.safariextension file is in ~/Library/Safari/Extensions. The installer places files in two locations: There is a JS Blocker folder in ~/Library/Caches//Extensions called JS Blocker 5.safariextension. Because of that you cannot use Safari to uninstall it. It chokes Safari every time I try to install it. This version of JS Blocker (5.0.19) is a total disaster. To stop this inexplicable popup warning, uninstall JS Blocker from your extensions. The old Gallery is being deprecated in favor of the a App Store equivalent anyway. Apparently, Apple hasn't yet cleaned out its Gallery of blocked extensions. 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. Sorry about this, but there's nothing I can do."īTW: If Safari give you a popup warning saying "Safari can't install this extension. JSB will never work again going forward unless Apple reverses this decision. "Apple has dropped support for what they deem "legacy extensions". If Apple does in the future allow for extensions like JS Blocker, I will be very grateful. JS Blocker was brilliant, incredibly useful and relatively easy to use. It no longer works with Safari and will not be updated to fit into Apple's requirements. JS Blocker is IMHO the most unfortunate casualty. Unfortunately, not all of Apple's choices in blocked extensions made sense. Apple's goal was to increase Safari security. Safari 12.0 radically changed its extension system.
