Well we may be noticing that there has been lots and lots of changes on Facebook. The most annoying change that we have ever faced is its the Chat. I have already given a tutorial on old fb chat. But still lots and lots of people complained about that and they changed it quite a better with scroll down feature with More Friends Online, so that the people online can be found easily. But the stickiness of the chat is still annoying. People have started using third party software/addons on their browsers. People would surely liked to get noticed that their Cookie/Sessions can be taken from such third party software.
