The Firefox Web browser includes tools to organize your favorite websites into bookmarks. The bookmark functionality lets you easily import and export bookmarks in a standard HTML file. Exporting bookmarks works well to back up your bookmarks, import them in another browser or share them with other people. The standard HTML file exported can even be used on a website. The import function accepts HTML files created by other browsers or by Firefox on another computer.
Open Firefox. Click the Bookmarks menu and select the "Show All Bookmarks" option. Click the "Import and Backup" menu at the top of the window that appears, it looks like a star icon.
Click the "Export HTML" option. Select and file name for the exported bookmarks. This same bookmarks library window lets you import bookmarks.
Click the "Import HTML" option in the Import and Backup menu. Click "Next" or "Continue" depending on your operating system. Select the file in the window that appears and click "Open."
