Question

I downloaded a plug-in from this site to change the look of my FB profile:

It has since began to post on each of my friends profiles as if it is a wonderful idea and it's not. Please help me delete it. It is not coming up as an application. It also utilized Firefox as a supporter or used its logo along with its promotion. It downloaded Bing as a toolbar as well.

That sounds like an unusual problem. Did it install as an Extension, or as a Plugin? Check in the Addons Manager, and check to see where it appears. If it appears in the Plugins area, then you can disable the plugin, killing its ability to do anything. If it is an Extension, it will be under the Extension section of the Addon Manager. Select to Uninstall and then allow it to do what needs to be done to remove it from your system. If nothing else works, you could try creating a new profile in Firefox and using it instead.
For more information about using the Firefox Profile Manager, I suggest you read [http://support.mozilla.com/en-US/kb/Managing%20profiles this] article on the Mozilla Support zone. While it does state that features such as the Profile Manager are for advanced users and developers, it can also be used in situations where an addon installs itself and you have difficulty removing it from a profile.
I suggest you open a program such as Notepad on Windows (or TextEdit on Mac OS X), and then note down the Extensions and Themes you make the most use of when browsing the internet. Generally, addons such as AdBlock Plus will rank highly on a list such as this, and they tend to be the first extensions I install.
If you do decide you want to customize your Facebook interface in the future, did you know there are several ways to do so with extensions for Firefox? Using [https://addons.mozilla.org/en-US/firefox/addon/stylish/ Stylish] and [https://addons.mozilla.org/en-US/firefox/addon/greasemonkey/ Greasemonkey], as well as their respective sites (Userstyles and Userscripts, respectively) can allow you to find some methods for tweaking your Facebook profile. Note that these customizations are local to you, as are the ones you initially attempted to install. In other words, they are only visible on your computer.
For example, if you were to customize your Facebook on your PC, and then use a friend's computer, you would not see the customizations, even if they were using Firefox as well. This means you can have your Facebook profile how you want it, without making it harder for others to see. I hope this is of help, and thanks for using Firefox!
