Facebook – How to hide from the friends notifications about me joining some Facebook groups

There are some new options.

How do I edit my notifications for my groups?

To change the notification settings for a Group you’re a member of, go to the Group and click the "Edit Notifications" button on the top right corner of the page.

Here is the current setup I have used.

On top of this on each post you make a comment on, you must click Unsubscribe so that you are not notified about it on Facebook every second.

This solved it for me. These are for new groups. I checked one of my old groups and it has not undergone this change. Any other tips feel free to comment.

As of 10/11/13:

1. Click on your name in top right corner
2. Click “Friends” at the top
   
3. Click the pencil image to “Manage”
   
4. Click “Edit Privacy”
   
5. Modify “Friend List” section by selecting from the drop down menu
   

If you have timeline (which I assume you have):

1. Go to your profile
2. Click on your friends list
   
3. Click on Edit
   
4. In the popup, click on the icon from the right—in this case the globe, but you might have a different icon, like friends
   
5. Select Only me (or whatever other option you want)
   

Is this what you are looking for?

1. Go to your profile and click Edit in the top right corner
2. From the menu in the left column, click Friends and Relationships
3. Go to the Friends section and use the audience selector on the right side to control who can see your friends
