This info from a fourm catering to Chimera users...
As for many of the comments here on importing bookmarks, click the little 'Book' icon - you'll see that your IE bookmarks are all imported automatically in a folder at the bottom - just drag them around to where you want them...
For importing Chimera bookmarks, its a little tricky, but only takes a minute:
1) Export bookmarks in Chimera (Manage Bookmarks menu item)
2) rename the file 'Favorites.html'
3) Trash: Users
Yourname):Library:Safari (folder)
4) Trash: Users
Yourname):Library
references:com.apple.safari.plist
5)Replace the file favorites.html in Users
Yourname):Library
references:Explorer with your exported _file.
6) Launch Safari
Now, when you click the book icon, you'll see the Imported IE Bookmarks folder now contains your Chimera Bookmarks.... move them where you want them (Toolbar or Menu)
