In a recent article, Facebook has revealed that it has changed the way it handles comments on its platform.

It has made the option of "hide" as default, while "show" is now only an option to the app itself. This means that if you are trying to hide comments that are tagged as friends, it will show them on your News Feed and your posts.

You will still be able to hide them if you wish, though. This also means that users who use "show" will not be shown on your News Feed anymore unless they are tagged as friends or you follow them.

With this extension, you can now view all the comments in a particular conversation, including those that were removed. You will be able to go back and change them, or just delete them.
