Hello, There are two ways of doing this: 1. '''Firefox Sync''' - if you want to continue using both Windows and Mac versions of Firefox then you can use Firefox Sync to keep your bookmarks and other settings synchronised between the devices. See here for set up instructions: [[How do I set up Firefox Sync?]] 2. '''Export as html and import''' - if you want to move permanently from Windows to Mac then I think the cleanest thing would be to export the bookmarks from Windows to HTML. Follow these instructions: [[Export Firefox bookmarks to an HTML file to back up or transfer bookmarks]] then transfer the HTML file to your mac and import them into Firefox there. Follow these instructions for the import: [[Import Bookmarks from a HTML file]] I hope that helps. Let me know if not.
