That's because it's not a browser. It's a search engine. The instructions talk about clicking on a magnifying glass in a search bar, but none of that is accessible to us screenreader user types. So instead, do this in Firefox, or the applicable thing in your Web browser of choice:


1. Open Firefox.

2. Open the Tools menu with Alt plus T.

3. In the search field type:


search engine


and press ENTER. You could type just the word "search," but that yields too many choices.

4. If you like, read the resulting page, or just shortcut the whole process by finding the combo box that shows your current default search engine.

5. To change it, tap the space bar or press ENTER, then use the vertical (Up/Down) arrow keys to select Duck Duck Go, and press ENTER to close the combo box, which will save your change.


All done.
