Here’s my brief tutorial for adding http://dictionary.reference.com as a bookmark on your toolbar.
This only works if you have Firefox. In this example we’ll add a “Web Tool” bookmark to the Firefox Toolbar for Dictionary.Reference.com. This will help when you need to quickly lookup a word.
1. Click here http://dictionary.reference.com

2. Once the page finishes loading, click on the “Bookmarks” menu at the top of the browser.

3. Click on the expand button to view your bookmark tree.

4. Select “Bookmarks Toolbar Folder” from the Bookmarks Tree.

5. You shoud now see the bookmark for Dictionary.com in your Firefox browser’s toolbar.

To add more bookmarks to the toolbar, repeat this proceedure, replacing the dictionary.reference.com url for the new toolbar bookmark
