While there currently isn't a way of importing all your RSS feeds into Safari 2 (in Tiger), here's a slightly roundabout method that works (I originally posted this at pimpmysafari.com):
You will need:
- Firefox, with the Sage RSS extension installed
- Safari 2
- In your RSS reader, export your feeds as a .opml file
- In Firefox, choose 'OPML import/export' from Sage's sidebar menu. Browse to your .opml file and continue. Note: I had problems with pressing the Continue button on my build; if you find it won't do anything, try double-clicking it.
- Once imported, close Firefox
- In Safari, choose 'Import bookmarks...' from the File menu, which will bring your RSS feeds in as a bookmark collection -- check the bookmark manager window. This will also import any other Firefox bookmarks, too, of course.
- To get Safari to register these as RSS feeds, open the imported feeds folder in tabs.
