How to Remove Safari Extensions on Mac



Safari for Mac allows for optional third party browser extensions to be installed, performing functions like social sharing, note taking, interface with apps like 1password, amongst others. Sometimes Safari extensions can be useful, but sometimes they are no longer needed, or they can be problematic and cause freezes or trouble with Safari or for the ability to work with a specific website, and accordingly users often need to delete extensions from the browser.



This article will show you how to easily remove Safari extensions on a Mac. It’s important to note that Safari Extensions are different from Safari Plug-ins, which are removed separately.


Removing Safari Extensions on a Mac from Safari

This works to delete any Safari extension in macOS or Mac OS X:

  1. Open the Safari app and go to “Safari” menu and choose “Preferences”
  2. Go to the “Extensions” tab
  3. Click on any extension you no longer want in Safari and choose “Uninstall”
  4. Confirm that you want to delete the selected extension from Safari to remove it
  5. Repeat with other extensions as necessary

This is the easy way to delete a Safari extension, but you can also manually intervene from the file system to remove extensions from Safari as well.

Manually Deleting Safari Extension on Mac

Sometimes if an extension is causing havoc with Safari, the Extensions manager won’t be able to load or the uninstall method above won’t work. This is somewhat rare, but it can happen in some particular haywire scenarios with an errant or incompatible extension that refuses to remove itself. If this happens, you can manually delete an extension by going to where Safari extensions are located in Mac OS and removing them, this is done with the following:

1. Quit Safari on the Mac
2. From the Finder, hit Command+Shift+G to bring up Go To Folder (also accessible from the Go menu) then enter the following path:  ~/Library/Safari/Extensions/
3. Choose “Go” and you’ll instantly be in the Safari Extensions folder on the Mac, delete any extensions you wish to remove from Safari

4. Relaunch Safari when finished

 Don’t forget the tilde ~ when entering the file path to signify the users Extensions folder.

What about removing Safari Plug-ins?

As mentioned earlier, Safari Extensions are different from Safari Plug-ins. Safari Plug-ins include more functionality and tend to be feature-rich media viewers, like Adobe Acrobat reader in Safari, Adobe Flash, Silverlight, QuickTime, and similar. Without going too in-depth in this particular walkthrough, you can locate Safari plug-ins at the following file paths on a Mac:

System Level Safari plug-ins location: (available for all users):

/Library/Internet Plug-ins/

User level Safari plug-ins location: (available only for current user):

~/Library/Internet Plug-ins/

Extensions and plug-ins are often the first place to look if you are troubleshooting Safari crashes and have already updated the software and removed the cache. This is particularly true if you are experiencing Safari difficulties after updating the browser, when some plugins and extensions have not yet been updated to be compatible with the latest version. For the most part, most users don’t really need any Safari extensions or third party plug-ins, and having a simpler Safari installation often can ward off difficulties with the browser on any Mac.

Reset DNS and chache Mac Snow Leopard and later


Learn how to reset (flush) the DNS cache.


About the DNS cache

OS X keeps a local cache of resolved DNS queries for a time defined by the DNS server. Sometimes it might be necessary to reset the cache immediately and re-query a DNS server. For example, you might need to do this if you are a network or server administrator and an entry on your DNS server has recently changed.

If your Mac isn't using the latest DNS entries from your server, you can restart your Mac to update its cached information. If you need to update DNS entries on a server using OS X and you can't restart the server, use the terminal commands below for the version of OS X you're using.

OS X Yosemite and later

Use the following Terminal command to reset the DNS cache in OS X v10.10.4 or later:

sudo killall -HUP mDNSResponder

Use the following Terminal command to reset the DNS cache in OS X v10.10 through v10.10.3:

sudo discoveryutil mdnsflushcache

OS X Mavericks, Mountain Lion, and Lion

Use the following Terminal command to reset the DNS cache in OS X v10.9.5 and earlier:

sudo killall -HUP mDNSResponder

Mac OS X Snow Leopard

Use the following Terminal command to reset the DNS cache in OS X v10.6 through v10.6.8:

sudo dscacheutil -flushcache

The Mac Hosts File: How to Modify /etc/hosts in OS X with TextEdit


Another Great tip from MacOSX Daily!



 The Mac hosts file is a system level file located at /etc/hosts which maps IP addresses to host names for Mac OS X networking. Many users edit and modify the hosts file so that they can point a domain to a different IP address, whether for the purpose of local development, blocking sites, or simply to access alternate servers from various apps and system level functions. Most advanced users will edit the hosts file from the OS X Terminal using nano or vim, but for those who prefer to stay within the Mac OS GUI, you can also modify the Mac’s hosts file through TextEdit, or even a third party app like BBEdit or TextWrangler. This offers a more user friendly option compared to going through the command line.

If you don’t have a specific reason to modify the Mac hosts file in OS X, you should not do so. An incorrectly formatted hosts file or improper entry can lead to DNS issues and problems with various internet services. This is for advanced users.

How to Modify the Mac Hosts File at /etc/hosts with TextEdit OS X

This approach to changing /etc/hosts with TextEdit works with any version of OS X. For Mac users who are running OS X 10.11 or later releases, you must first disable SIP protection however, otherwise the Mac /etc/hosts file will be locked when attempting to access it from TextEdit.

    Quit TextEdit if it is currently open
    Launch the Terminal application in Mac OS X, found within /Applications/Utilities/
    Enter the following command exactly to open the Macs hosts file within the TextEdit GUI application

    sudo open -a TextEdit /etc/hosts

    Hit return and enter the admin password for OS X when requested to authenticate the launch through sudo


    The /etc/hosts file will launch into TextEdit as a plain text file where it can be edited and modified as need be, when finished use File > Save or hit Command+S as usual to save the changes to the hosts document *

Quit out of TextEdit, then quit out of Terminal when finished


* If the hosts file shows as “locked” and won’t save changes despite being launched through sudo, it’s likely because you didn’t disable SIP as mentioned in the introduction. You can turn off SIP in OS X with these instructions, which requires a reboot of the Mac. This is necessary for modern versions of OS X, though you can choose to edit the hosts file using the command line with nano as described here without adjusting SIP.

It’s good practice to make a duplicate of the hosts file so that if you break something you can easily fix it, though we’ve got the original default hosts file here in case you need to restore it. It’s also a good idea to set plain text mode as the default for TextEdit.

You’ll likely want to clear out your DNS cache after modifying the hosts file, here’s how to flush DNS in OS X El Capitan and modern versions Mac OS and how to do the same in prior releases.

Users can also choose to modify Mac OS X’s /etc/hosts with TextWrangler, BBEdit, or another third party application. The trick is largely the same as Text Edit, still requiring the use of sudo, but changing the specified application name as follows.

Opening /etc/hosts with TextWrangler:

sudo open -a TextWrangler /etc/hosts

Or launching /etc/hosts into Bbedit:

sudo open -a BBEdit /etc/hosts

While the aforementioned approaches work in all modern versions of OS X, earlier versions of Mac OS X can also launch the TextEdit binary with hosts directly from the command line with the following syntax:

sudo ./Applications/ /etc/hosts

That method will not work in the latest releases, however, thus you’ll want to rely on the open command instead.

Do NOT fall for the domain sale email scam!


There seems to be people out there with too much time on their hands and they are trying to scam you out of money and time. They send out emails to registered domain owners telling them that there is there own or another domain similar to theirs for sale. Some will ask for money in the email others will just  ask you to seriously inquire about the sale.

Here is what has to say about it...remember this is an older article -- however, the insight does still apply to this and other types of info finding (phishing) scams.



I just found the following email sent to us in our easyDNS support queue:

From: Global Domains International
Subject: Regarding your domain name
Date: Tue, 01 May 2012 17:01:41 +0400
To: From: Global Domains International

Hello, I have the .COM version of your domain name for sale.

Would you be interested in buying the domain for $250 seeing as though
you own the same domain but in another extension ?

We can use Escrow for the transfer and I will cover the fees.
Let me know

Thankyou Shawn.
Global Domains International


How The Scam Works

The first time I saw this one, I figured that the guy on the other end simply screwed up, because when I went to check the whois record for the domain I realized that he hadn’t registered the domain yet!

I figured “his screw-up, our gain”, and I simply hand-registered the domain myself. No need to spend $250 on a simple domain registration on an unregistered domain that matched one we already owned.

Then I got the exact same thing for another domain a little while later and I finally realized what was happening: it was just another domain registration scam.

All these guys do is harvest the public records for domain registrations, then look for “gaps”, where a .com may still be available for a .net that is registered. They compile a list of these “targets” and then email the .net domain holders.

If any of them “bite” and agree to buy the .com version then all they do is hand register the domain themselves on spot and turn around and sell it to you for $250! Instant arbitrage.

So every time I see these emails now I simply hand register the domain for a fraction of the price.

Save Yourself the Trouble of a Legal Hassle

The other aspect of these emails are that they are deliberately targeting domains you already own, relying on your desire to “defend your mark” to agree to their terms. Their price is $250, about 1/10th what it would cost you to launch a domain dispute against them if they really owned the name.

If they did really own the domain names they are trying to sell to unwitting registrants, what they are doing is a near-textbook case for a Domain Dispute Proceeding or “UDRP” (Universal Domain Resolution Protocol).

(Remember the following if you ever find yourself facing somebody offering to sell you a variation of your name for real:)

Under the UDRP, a domain registrant must be able to prove 3 things in order to have a domain name transferred from a third party to themselves:

  1. That the person who registered the domain has no legitimate interests in the domain
  2. That your business is or could be impaired by the confusion caused by their ownership of this name.
  3. An element of “Bad Faith” – that is that they registered the name with the implicit intent to either impair your brand/mark or to profit by selling it to you.

Had the scammers sending these emails really registered the alternative versions of these domains they would lose any UDRP launched against them  – but it would cost 10 times as much as simply buying it from them.

This is the logic they are relying on when they send these scams out.

Don’t fall for it:

  • When you register a domain name and want to “lock it up”, try to get the following versions: .com, .net, .org and the country-code domains of your home country, i.e. .ca or .de
  • The rest of the variations you can probably not worry about. There is another scam trying to get you to register your name in obscure foreign country codes.

More on that one in another email.
