Firefox and CC Search
A plugin for the Creative Commons search tool is built into some versions of the Firefox web browser. On most versions, the search box defaults to using Google. You can change your search engine by clicking on the small black arrow in the search bar. See the screenshot below.
Using the drop down menu pictured above you can access the Creative Commons search tool or any other installed search engine plugin. Note that your search engine choice can only be set by you. Creative Commons never switches it for you, nor do we have any technical means to hijack the searchbar.
Click on the logo that appears in the search box (the CC logo, or the Google logo, for example). You will see a pull down menu that allows you to use your mouse to select a different search provider. Choosing "Manage search engines" allows you to add or remove search engines of our choice, such as Flickr and Wikipedia.
It's easy to switch between search providers through the keyboard as well. Start by clicking inside the search box, then hold down the Ctrl key (or the Apple key on a Mac) and press the up arrow. After a few presses of the up arrow, you should see the Google logo. To change to other providers, you can press Ctrl (or Apple) + down. Pressing this key combination accidentally is often the way most people enable the CC search without knowing it!
If you don't have Firefox, you can get it from http://getfirefox.com
