Gentlemen,

Many thanks.

When I first encountered the missing bookmarks, the Firefox help page suggested that a simple restart might restore the bookmarks; so I restarted but that didn't help. That's also probably why the System Restore didn't work in this instance, as Lawrie mentioned. Great suggestion though for any future problems!

Firefox was superior to IE when I first came across it years ago, but after the first upgrade, I wanted to uninstall it. I searched the web and seems many users did too, but it wasn't easy. I still have IE.
