Get rid of distractions! This add-on puts a simple button at the bottom of your screen to turn your Facebook timeline on and off. You can still message people, see events, search for people, etc. but no more wasting time on boring timeline updates!
Here is what the developer of this add-on had to say about it:
A Facebook button with a giant X over it (in the bottom right side of your browser screen) will show up after installing. If you click this button while you’re signed into Facebook, your timeline will be hidden! If you click it again, it’ll be back. This way you can keep Facebook open to message people, but you won’t get distracted by your friends timeline updates streaming by forever.
You can pick up Facebook Timeline Toggle from the Firefox Add-ons website.
