Safari shows Blocked Plug-In error for a few PDFs

I get exactly the same here. As we have nothing like the same Machine or OS, I doubt there's anything 'wrong' with your install.
This looks like some remote plugin was activated - some ancient Flash, Silverlight or Java etc, which have long been blocked in Mac & really shouldn't be unblocked.

It does work if you right click, download the link instead.

Poking at the page with debug tools I get

[Error] Refused to apply a stylesheet because its hash, its nonce, or 'unsafe-inline' does not appear in the style-src directive of the Content Security Policy. (KVSH-Newsletter_2021_06_11_Impf-Update11.pdf, line 0) [Error] Refused to load https://www.kvsh.de/fileadmin/user_upload/dokumente/Praxis/Praxisfuehrung/Newsletter/2021/KVSH-Newsletter_2021_06_11_Impf-Update11.pdf because it does not appear in the object-src directive of the Content Security Policy.

though I'm just stumbling in the dark in the developer tools, tbh.

How To Unblock Plug-ins And Fix Blocked Flash Websites On Mac

Some Safari plug-ins typically get blocked after a security update, particularly when Apple deems plug-ins as potentially risky until the developer provides an app upgrade. Truth be told, Apple prevents plug-ins for your protection. However, it can be annoying to have a trusted and essential plug-in get blocked while you work and browse the Internet. In this article, we’ll show you how to unblock plugins on and also give you tips on how to unblock flash websites on Mac. So, read on!

How to Enable Plug-ins in Safari

If your plug-ins have been disabled in Safari, here’s how you can re-enable them:

  • Go to Safari > Preferences.
  • Click Security.
  • Check the box beside Allow Plug-ins.

Doing this will enable all plug-ins. If there are plug-ins that you no longer use, this can also be your chance to manage your plug-ins and just enable specific ones.

  • Go to Safari > Preferences.
  • Click Security.
  • Click Website Settings beside Allow Plug-ins.
  • You will be shown a list of plug-ins. Select the plug-in you want to enable from the menu.

  • Click Done.

How to Unblock Flash Websites on Mac

More often than not, the blocked plug-in is Adobe Flash, which can be problematic if you frequent Flash-based websites. Flash has been a frequent target for unscrupulous online activities, that is why it gets blocked. A website’s Flash plug-in needs to be updated frequently to avoid being included in the Safari block list. To unblock a Flash website or plug-in, update it first. If you get an alert saying that your Flash is outdated, here’s how to update it:

  • Click the arrow at the right side of the Flash out-of-date icon.
  • Click Download Flash in the alert window.
  • Once downloaded, open the Install_Flash_Player file, which can be found in your Downloads folder.
  • Double-click the Install Flash Player icon.
  • Click Open.
  • Check the box beside the I have read and agreed to the terms of Flash Player Licenses Agreement statement.
  • Click Install.

One final tip: To get the most out of your Mac and make sure it is in excellent condition at all times, we suggest you download and install Outbyte macAries. By removing junk files and boosting your RAM, this allows for a faster user experience.

How to fix 'Blocked Plug-in' in Safari

One of the issue that Safari users often research online is the 'Blocked Plug-in' error message. Typically, the reasons why you may see this message are multiple. Sometimes it is because your Safari Web browser is outdated, or because some of the extensions you use have pending updates. While outdated software is the typical cause of the problem, there could be other reasons for the 'Blocked Plug-in' in Safari error – such as corrupted files.

The 'Blocked Plug-in' in Safari error may occur when performing certain actions – trying to play an online video, or trying to view a PDF document. The former may happen when trying to view Adobe Flash Player media. This technology is now defunct, and it is no longer officially supported by Adobe or other software vendors. However, some old websites may still rely on some content, and visiting them is likely to result in the 'Blocked Plug-in' Error. Typically, users who encounter this issue, end up enabling Adobe Flash Player temporarily. You should know that this is a major security concern – Flash Player has been the target of cybercriminals for years.

How to fix the 'Blocked Plug-in' in Safari

There are several errors to tackle the problem, and all of them are very easy to apply.

  • Update the plug-in causing the problem. If you see the issue when attempting to view a PDF, then the add-on for PDF documents needs an update. If it is a Flash Player issue, then you may want to try downloading the latest available update from Adobe's website.
  • Apply browser updates. Outdated Safari is another likely cause of the problem, so make sure to check for pending system and browser updates.
  • Re-enable plug-ins. The 'Blocked Plug-in' in Safari message may appear because an extension is disabled. You should head to Safari -> Preferences -> Websites and then enable add-ons that the website may want to use.

How To Fix 'Blocked Plug-in' in Safari

For years, plug-ins have been helpful components intended to expand the functionality of programs such as Web browsers. They were essential for various content types to be supported and displayed properly. However, most plug-ins have been released by third parties and have become associated with system vulnerabilities and security issues historically. As such, many browsers have begun moving away from the need for plug-ins by natively integrating a lot of that functionality. 

Still, users may encounter a 'Blocked Plug-in' error message in Safari. Usually, the message indicates that the system has stopped a specific plug-in from executing. In most cases, an incompatibility issue between the browser and the version of the plug-in might have been detected. You can try updating either the Safari browser or the malfunctioning plug-in, depending on which one has an update available. You also can try to enable it in the browser manually:

  1. Select the Safari menu.
  2. Choose 'Preferences.'
  3. Select the 'Websites' tab.
  4. Go to the list of installed plug-ins, select the one you want, and check its corresponding box to enable it. 

'Blocked Plug-in' could Indicate Threatening Actions

The presence of the 'Blocked Plug-in' may not always be a signal of a benign problem. It also could be exploited by a corrupted application or a browser extension, in an attempt to trick the user. If such applications are present on the Mac, they could show fake 'Blocked Plug-in' errors that urge the user to update a specific plug-in by clicking on the 'conveniently' provided button. Doing so could trigger a redirect to a questionable or unsafe website. Users may land on online tactics, fake giveaways, phishing pages, or domains promoting PUPs (Potentially Unwanted Programs). The scheme also could lead to serious malware threats. To mitigate the chances of such negative outcomes, it is recommended to perform thorough scans of your Mac with a professional security solution regularly.

How to fix the 'blocked plugin' error

Home

When you see a "blocked plugin" error message on a black screen when a screensaver starts, this means a plug-in — a third-party program required by the screensaver — is not working. In 99% of the cases, the plug-in in question is the Adobe Flash Player, and the solution is to update Flash to the latest version, as Apple blocks outdated versions for security reasons.

It is also possible you have never installed the required plug-in on your computer. Whatever the case is, this help page will guide you through the actions required to fix the problem.

Because the "blocked plugin" message can be hidden by some screensavers, the solution provided here may also apply to Mac screensavers that stop working but show no errors.

Checking for updates

Follow these steps to check for updates to the Adobe Flash Player. Alternatively, you can re-install the plug-in using the instructions below "(Re-)installing the Adobe Flash Player".

  1. Click the Apple icon in the top left of your screen
  2. Click "System Preferences"
  3. Check for a "Flash Player" link in the bottom row of the System Preferences panel
  4. If a "Flash Player" link is shown, click it and continue with the next step. If not, skip ahead to the "(Re-)installing Adobe Flash Player" section below
  5. The "Flash Player" panel will open. Click the "Updates" tab
  6. Click the "Check Now" button to check for available updates
  7. If an update is available, you will be notified and forwarded to the Adobe website
  8. Follow the instructions on the Adobe website to install the Flash Player update

If no updates are available, you can try clearing "all local storage, saved choices, settings and other data used by content in Flash Player" from the "Advanced" tab of the Flash Player panel. Note that this will reset the settings of other applications that rely on Flash.

(Re-)installing the Adobe Flash Player

To install the Adobe Flash Player plug-in for the first time, or to update it to the latest version without checking for updates first, follow these steps:

  1. Go to https://get.adobe.com/flashplayer/otherversions/
  2. Beneath "Step 1", select "Mac OS X"
  3. Beneath "Step 2", select "FP X Mac for Safari and Firefox - NPAPI (where X is a number)
  4. Click the "Download now" button to begin downloading the plug-in
  5. Once your download is complete, open the file that was downloaded to show its contents in the Finder, then double-click "Install Adobe Flash Player.app"
  6. Follow the instructions of the installer to complete the installation process

You now have the latest version of the Adobe Flash Player plug-in. The next time your screensaver starts, you should no longer see the "blocked plugin" error message.

How to remove blocked plug-in on Mac

This article explains the rationale behind a blocked plug-in on Mac and provides a workaround for the error, including a way to remove the misbehaving app.

Update: October 2021

Plug-ins are intended to make sure a system component, such as a web browser, supports certain features or types of content provided by websites and other modern electronic services. This is an important prerequisite for delivering a proper user experience, but with the caveat that these enhancements largely have a third-party nature and may become a source of security issues. An error on Mac saying “Blocked Plug-in” typically means that the system has prevented a specific plug-in from running. Most reports regarding this issue are associated with Adobe software, including Flash Player and Acrobat Reader. For instance, the alert may occur when a user tries to open an email link in Safari leading to a PDF document. The file preview turns out to be a no-go in this case as the browser displays a black screen with the above-mentioned message in the center. Incidentally, this can be a cross-browser issue and hold true for Chrome and Firefox as well.

‘Blocked Plug-in’ error in Safari

One more scenario that falls under the same category is when a Mac user goes to a website that relies on Adobe Flash Player to interact with the visitors. A common situation involves watching multimedia or playing an in-page game. The “Blocked Plug-in” error may show up alongside a notification saying that the content requires the latest version of the Flash Player. Why would Apple pull the plug on a plug-in (pardon the linguistic redundancy)? In the case of Flash, things are fairly clear. This software has gained notoriety for being crammed up with vulnerabilities. Although Adobe is releasing patches off and on, computers running it may stay susceptible to cybercriminals’ attacks for months. Arbitrary code execution and data theft are among the biggest issues stemming from these imperfections. Moreover, the vendor is rumored to plan on ending support of Flash Player in 2020 and it will be eventually disabled from major web browsers by default. As a matter of fact, Apple has already done it since Safari 10, but users can still turn on the plug-in if they need it.

Special Offer
“Blocked Plug-in” error virus may re-infect your Mac multiple times unless you delete all of its fragments, including hidden ones. Therefore, it is recommended to download Combo Cleaner and scan your system for these stubborn files. This way, you may reduce the cleanup time from hours to minutes. Download NowLearn how ComboCleaner works. If the utility spots malicious code, you will need to buy a license to get rid of it.

In addition to the obvious legit causes for macOS to block a plug-in, there is a shadier course of action that involves the error messages in question. Malware distributors might try to ambush a user by misreporting a bug of that kind. To execute this hoax, perpetrators use a potentially unwanted application (PUA) that hijacks the victim’s web browser and either forwards the traffic to sketchy sites or triggers misleading popup warnings. This type of a malvertising campaign is accompanied by “Missing Plug-in” or “Blocked Plug-in” alerts. Unlike valid system notifications, these ones will typically include a button to download the latest build of the “enhancement” tool. However, instead of installing the software, this routine results in depositing a malicious app such as adware that will embed sponsored links and display ads across the visited web pages. Scareware is another common form of harmful code doing the rounds this way.

If “Blocked Plug-in” errors are actually shown by macOS for security reasons or to maintain system stability, there are several things that should sort it out. Before moving on to the troubleshooting, it’s worth pointing out that the benign instance of disabling of a random plug-in usually occurs right after an upgrade to a new system version that introduces a change in handling third-party applications. Let’s now zoom back into the repair. Here are a few techniques every effected Mac user should try first:

  • Update the plug-in. First things first, the applet may have been blocked because it’s way out of date. If so, the starting point of the fix is to determine which plug-in cannot be launched. If the error pops up when you are trying to preview a PDF file received over email, then go to get.adobe.com and download the newest iteration of Acrobat Reader. If it’s a Flash Player issue, then install the most recent release of the program from the above site.
  • Make sure Safari is up to date. Note that the “Blocked Plug-in” alert is mostly a Safari issue. If you are using macOS Big Sur, then you already have the latest version of the browser and you can skip this step. For earlier versions of the operating system, click the App Store icon in the Dock, go to the Updates tab, and check if there is a newer version of Safari or whatever browser is acting up. Apply the update if available.
  • Re-enable the plug-in manually. Expand the Safari menu and select Preferences. Click the Websites tab (on older macOS versions, go to Security tab). The bottom part of the left-hand navigation bar reflects the list of installed plug-ins and their current status. Find the right entry and check the box next to it to enable the plug-in. You can configure the app to only run on specific sites, too.

If the above steps don’t rid you of the “Blocked Plug-in” error, chances are that it’s caused by malicious activity on your Mac. To address the predicament, you need to check the computer for unwanted code and remove it for good. The sections below will walk you through this process.

Blocked plug-in error virus manual removal for Mac

The steps listed below will walk you through the removal of this malicious application. Be sure to follow the instructions in the specified order.

  1. Expand the Go menu in your Mac’s Finder bar and select Utilities as shown below.

    Go to Utilities

  2. Locate the Activity Monitor icon on the Utilities screen and double-click on it.

    Select the Activity Monitor

  3. In the Activity Monitor app, look for a process that appears suspicious. To narrow down your search, focus on unfamiliar resource-intensive entries on the list. Keep in mind that its name isn’t necessarily related to the way the threat is manifesting itself, so you’ll need to trust your own judgement. If you pinpoint the culprit, select it and click on the Stop icon in the upper left-hand corner of the screen.

    Stop malicious process

  4. When a follow-up dialog pops up asking if you are sure you want to quit the troublemaking process, select the Force Quit option.

    Select the Force Quit option

  5. Click on the Go menu icon in the Finder again and select Go to Folder. You can as well use the Command-Shift-G keyboard shortcut.

    Use the Go to Folder feature

  6. Type /Library/LaunchAgents in the folder search dialog and click on the Go button.

    Open /Library/LaunchAgents folder

  7. Examine the contents of the LaunchAgents folder for dubious-looking items. Be advised that the names of files spawned by malware may give no clear clues that they are malicious, so you should look for recently added entities that appear to deviate from the norm.

    As an illustration, here are several examples of LaunchAgents related to mainstream Mac infections: com.pcv.hlpramc.plist, com.updater.mcy.plist, com.avickUpd.plist, and com.msp.agent.plist. If you spot files that don’t belong on the list, go ahead and drag them to the Trash.

    Root-level LaunchAgents folder contents

  8. Use the Go to Folder lookup feature again to navigate to the folder named ~/Library/Application Support (note the tilde symbol prepended to the path).

    Open ~/Library/Application Support folder

  9. When the Application Support directory is opened, identify recently generated suspicious folders in it and send them to the Trash. A quick tip is to look for items whose names have nothing to do with Apple products or apps you knowingly installed. A few examples of known-malicious folder names are UtilityParze, ProgressSite, and IdeaShared.

    Application Support folder contents

  10. Enter ~/Library/LaunchAgents string (don’t forget to include the tilde character) in the Go to Folder search area.

    Open ~/Library/LaunchAgents directory

  11. Look for dodgy items related to the blocked plug-in error virus (see logic highlighted in subsections above) and drag the suspects to the Trash.

    Contents of LaunchAgents folder in user’s home directory

  12. Type /Library/LaunchDaemons in the Go to Folder search field.

    Go to /Library/LaunchDaemons

  13. In the LaunchDaemons path, try to pinpoint the files the malware is using for persistence. Several examples of such items cropped by Mac infections are com.pplauncher.plist, com.startup.plist, and com.ExpertModuleSearchDaemon.plist. Delete the sketchy files immediately.

    LaunchDaemons folder contents

  14. Click on the Go menu icon in your Mac’s Finder and select Applications on the list.

    Go to Applications screen on Mac

  15. Find the entry for an app that clearly doesn’t belong there and move it to the Trash. If this action requires your admin password for confirmation, go ahead and enter it.

    Drag malicious app to the Trash

  16. Expand the Apple menu and select System Preferences.

    Select System Preferences

    Open System Preferences

  17. Proceed to Users & Groups and click on the Login Items tab.

    Proceed to Users & Groups

    The system will display the list of items launched when the computer is starting up. Locate the potentially unwanted app there and click on the “-” (minus) button.

    Delete unwanted login item

  18. Now select Profiles under System Preferences. Look for a malicious item in the left-hand sidebar. Several examples of configuration profiles created by Mac adware include TechSignalSearch, MainSearchPlatform, AdminPrefs, and Chrome Settings. Select the offending entity and click on the minus sign at the bottom to eliminate it.

    Select Profiles under System Preferences

    Remove malicious configuration profile from Mac

    If your Mac has been infiltrated by adware, the infection will most likely continue to hold sway over your default web browser even after you remove the underlying application along with its components sprinkled around the system. Use the browser cleanup instructions below to address the remaining consequences of this attack.

FAQ

What is block plugin?

A plugin can be blocked on your Mac for two reasons. First, it may not run if it’s out of date and lacks functionality to fully support your current software. The other scenario kicks in when Apple prevents a specific plugin from being executed due to compatibility issues or security concerns. The latter situation is far more common, given the Mac maker’s hardening control over the ecosystem of third-party code. If a plugin – which is technically a piece of software – fails to pass macOS notarization checks, you won’t be able to launch it and view web content that uses this potentially harmful entity.

How do I unblock a plug-in on my Mac?

Apple has been changing things a bit in this regard. All of your previously installed Safari plugins used to be listed under the “Security” tab of the browser’s Preferences screen. If you are using the latest Safari version, though, the bulk of this logic has migrated into the “Websites” tab. It allows you to specify permissions for websites to use specific plug-ins and features. In most cases, the original configuration of the item called “Reader” gives Mac users a hard time and causes the “Blocked Plug-in” alert. To get around this obstacle, click this entry in the sidebar and select “On” next to the relevant site.

There are also extensions listed under the eponymous Safari Preferences tab that displays your add-ons along with their current statuses. If you discover that an extension you need has been disabled, you can unblock it by putting a checkmark next to its name. Before doing it, make sure this item is legitimate and won’t harm your system. It is recommended to stick with extensions available on the official App Store. They are extensively checked for dubious activity and updated automatically.

How do I stop blocked plugins on Mac?

If a plugin is blocked on Mac, there is no need to stop it additionally. It won’t run anyway. In case you need the plugin to work again, open Safari, head to Preferences, click the “Websites” tab, select the blocked plugin in the sidebar, and change the setting for a particular website from “Off” to “On”. This will allow the content to be displayed on that resource. If you are sure that it’s safe to allow the plugin on all websites, simply select “On” next to the option at the bottom that says, “When visiting other websites”.
