If you want to use your bookmarks from a different web browser in Safari, you can export them from that web browser as an HTML file and then import them into Safari.
Open the other web browser.
Find the web browser’s Export Bookmarks option, and then choose it. The Export Bookmarks option is normally in the File menu.
Save the bookmarks as an HTML file; for example, “bookmarks.html.”
Open Safari and choose File > Import Bookmarks.
Select the HTML file you created, and then click Import (on Windows computers click Open).
