The Mozilla Navigator Sidebar
The sidebar is located on the left of the Mozilla Navigator screen.
To access the contents of any sidebar tab, click on its name. To close a sidebar tab, you must open another one. The sidebar contains the following tabs by default:
What's Related — Click on this tab to see a list of other websites that are related to the one you are currently viewing. Go to the Navigator => Smart Browsing section of Mozilla's preferences to have the What's Related tool ignore certain websites.
Search — The Search tab opens a screen in the sidebar where you can do a search for websites using a keyword or phrase and see the results without having to leave the site you are currently viewing.
Bookmarks — You can add sites that you like or visit often to your bookmark list for easy access. When you find a site you want to add, click on Bookmarks => Add Current Page.
History — The History tab shows a list of the sites you have visited. You can set determine how many days the history tab will store sites before clearing them by going to Edit => Preferences and going to History under the Navigation option.
The sidebar can be customized by clicking on the Tabs button that appears at the top of the sidebar list and selecting Customize My Sidebar. This opens a screen where you can add tabs to and remove tabs from your sidebar, and search for additional sidebar tabs online.
Click on Tabs and select Sidebar Directory to go straight to the Internet where you can browse through and choose websites to add as new sidebar tabs (similar to bookmarking them). Select a site and you will be asked to confirm the selection before the new tab is added.
