Bookmarks offer a convenient way of saving links to your favorite Web sites. Firefox not only makes it very easy to add new bookmarks with just one mouse click, it also offers multiple ways to manage large bookmark collections. You can sort bookmarks into folders, classify them with tags, or filter them with smart bookmark folders.
Add a bookmark by clicking the star in the location bar. The star will turn blue to indicate the page was bookmarked. The bookmark will be saved in the Unsorted Bookmarks folder under the page title. To change the name and folder of your bookmark or add tags, after bookmarking, click the star again. This will open a pop-up where you can make your changes.
To bookmark all open tabs, right-click in a tab and choose Bookmark All Tabs. Firefox asks you to create a new folder for the tab links.
To remove a bookmark, open the bookmarked location. Then, click the star and click Remove Bookmark.
