Disabling Facebook chat in browser

I wanted to turn off the Facebook chat “bar” at the bottom of each browser window when browsing Facebook, as I use Facebook Chat via Empathy (a real IM client), so I had no need for annoying chat windows popping up in the browser.

Quick easy fix – I use Adblock Plus in Firefox, so just filter out the following:

facebook.com#div(id*=presence)

And, job done – no more Facebook chat bar!
