If importing from an HTML file or another browser, you can find the import function by clicking the three vertical dots in the chrome address bar, select “Bookmarks” then “Import Bookmarks and Settings”. After you import these links, you can move them into your shared folder. You can copy/paste directly from the Bookmark bar or use the Bookmark Manager in Chrome.
In Firefox, you can also copy/paste directly from the Bookmark bar or from the Library. To access the Library, select "Show all bookmarks" on Firefox under the Bookmarks tab on the menu bar. OR use the option button (three horizontal lines at the top-right) to get to the Library
