Safari pop-up preferences missing

Try the Safe Mode to see if it shows there.

Might be a corrupt .plist.

Do a backup, preferably 2 backups on 2 separate drives.

Quit the application.

Go to Finder and select your user/home folder. With that Finder window as the front window, either select Finder/View/Show View options or go command - J.  When the View options opens, check ’Show Library Folder’. That should make your user library folder visible in your user/home folder.  Select Library. Then go to Preferences/com.apple.Safari.plist.  Move the .plist to your desktop.

Restart the computer, open the application, and test. If it works okay, delete the plist from the desktop.

If the application is the same, return the .plist to where you got it from, overwriting the newer one.

This may require a reset of some other Preferences.

Hello sergekills,

Thank you for using Apple Support Communities!

I understand from your post that you are not seeing the pop-up settings for Safari. These settings are located under Safari > Preferences > Security as described in the article below:

How to block pop-ups in Safari - Apple Support

Best Regards.

Try setting up another admin user account to see if the same problem continues. Please post back on whether or not this worked. Also try the Safe Mode. Please post back on whether or not this worked.

Well

At least I'm not the only one with the missing pop up blocker. Works fine in alternate user account as well. I've deleted every safari preference file and cache i could find, doesn't solve the issue. I'm not really sure when it started as I don't seem to be getting pop ups. But I first noticed it when I decided to run the uninstall flash program to remove the flash plug in, I'm on the latest version of Mojave but also Safari 12.1.1, Good luck if you find any solution. I'm hoping the next OS update will fix it.

Hi I was finally able to get the pop up blocker control back in Safari preferences by locating and deleting the safari.plist file.

It's in your user library. To get to it (in your user account with the issue) click Go in the Finder menu then hold down the option key on your keyboard, then click library. This will take you to your user library settings.

Then go to Containers/com.apple.Safari/Data/Library/Preferences/com.apple.Safari.plist and delete that file.

This will reset all your personal Safari preferences such as the toolbar and any settings for Safari back to their defaults but you won't lose any of your bookmarks or iCloud syncing. The pop up setting should then be available for you again in your main user account!

Cheers!

I forgot to include to restart your Mac after deleting the .plist file. Once you open Safari after restarting a new .plist file gets created.

You are welcome.

Yeah great! That plist file was apparently moved in mojave. Easier to find in Sierra
