Like so many others have reported, when I try to enable bookmarks sync using iCloud for Windows, it says I need to install the iCloud Bookmarks add-on for Firefox. But it's already installed and enabled. Looks like i’ll Have to reinstall Chrome :-(

Like several others here, iCloud for Windows keeps telling me I need to install the Firefox extension even though it's already installed an enabled.

UPDATE: Even though it doesn't show as checked in the iCloud for Windows settings, it is syncing bookmarks with iCloud.
