Are you dealing from a full deck? You posted here with a version of Firefox that was last "updated" almost two years ago.

See this article. Hope you're a speed reader and a whiz at comprehension, 'cause 5 minutes is a tough demand to meet - LOL. https://support.mozilla.com/en-US/kb/Lost+Bookmarks

Well, probably not. At my age a few cards may have been lost along the way! Anyway thanks for your time and trouble. One question? What's two years if the system is working just fine?

For one thing, Firefox 3.6 has a new feature where the Profile folder can be opened thru a new Menu item called Troubleshooting Information, which is located in the Help menu. That feature makes it a lot easier to get to where your personal data like Bookmarks are stored. For another, there have been a lot of stability fixes since 3.0.3 which lessen the chance of losing your bookmarks to begin with.

I lost a few myself over the last 6 decades, and many of those that are left are pretty dog-eared, but I started with a Canasta deck.
