To import or export bookmarks:
To import bookmarks, choose File > Import Bookmarks..., and then double-click the file that contains the bookmarks you want to import. Normally the file will have “.html” at the end of its name.
If you don’t have a file to import, or can’t find the file, you may need to export the bookmarks from the other browser.
To export bookmarks, choose File > Export Bookmarks..., and specify a location for the exported file. The file’s name will be “Webbla bookmarks.html.” Most browsers are able to import this type of file.
