Extensions are a type of add-on that allows you to do more with Firefox than just surf the Internet. For example, the Page Zoom Buttons extension provides a quick and easy way to control Firefox's full page zoom feature, and Theme Font & Size Changer allows you to choose your own font and font size for Firefox's interface.

The extensions that are recommended on Access Firefox were selected to help people with different disabilities to use Firefox and the Internet in a way that meets their individual needs.
