What are Add-ons and do I need them?
Add-ons are specific pieces of functionality or tweaks that are not part of the installed product. Plug-ins, similar to add-ons, allow the browser to display various files that it cannot natively display. For example, Flash files require the Adobe Flash player software to view. When you first access a Flash-enabled web site, you will be asked if you want to install a plug-in.
