Are you constantly annoyed by all those Facebook ads popping up on your timeline and also on the sidebar. Although personally I am not against such advertisements because they can be the bread and butter of a website that you are using for free, but since Facebook allows you to block and unblock advertisements, it’s no harm in knowing how to do that.
In order to block or disable all Facebook ads, you need to go to settings first.
In the proceeding screen you will find the link that you want, on the left sidebar.
In the Facebook Adverts section you can control the blocking and unblocking of two advertisement sources, viz., from third parties, and from your friends.
The advertisements that come from your friends might be them liking some Facebook page of a brand or company and then the notification showing up on your timeline, or some ad being created due to their action. Anyway, this is how you disable Facebook ads from third parties:
In the “Adverts shown by third parties” click “Edit third party adverts settings”.
From the drop down options, just select “No one” and then click “Save changes”.
Then go back, (using your browser back button)
Now you can do the same in the “Adverts and friends” section. Once you have done that, all the ads from third parties as well as your friends will be disabled on Facebook.
