If you’ve been using emoticons in Facebook chat, or really any instant messaging service, you probably already know them all.
Don’t want to see any of these smilies clogging up your comments? There’s no legitimate way to disable smilies directly on Facebook, but you can use the browser extension F.B. Purity to hide them. – Firefox add-on
– Chrome extension
Just install FBPurity in your browser, then open the FBPurity options page and type the following custom CSS code in the “Custom Text Filter” box.
The above code will also disable smilies in the chat, but if you just want to disable emoticons in comments, use the following.
This browser extension has been really popular for hiding the Timeline and News Ticker in the past, which means it can do a lot more than just hide smilies.
So, make sure to read up on the full add-on before you jump right in. For now, it’s all we have until Facebook adds an official option, which will most likely be never.
