The same thing happened to me but I solved it. It turns out that I had dragged my bookmark toolbar items off my bookmark toolbar and on to my menu bar in a previous version of firefox to save space. BUT, in firefox 4 - unlike previous versions - the menu bar is hidden by default.

To solve this you need to unhide the menu bar (right click on any toolbar at the top to see the option to do this), then if you can now see your bookmarks, either leave the menu toolbar unhidden, or once unhidden go into customize mode (right click on the toolbar and select customize) then you can drag the bookmark toolbar items off the menu bar and down to the empty bookmarks toolbar. After this you can hide the menu bar again as your bookmark menu items will be back on the menu toolbar again.

Thanks, but that doesn't help. When I said "turn on" the bookmark toolbar, I should have said "unhide." I figured that out very quickly. The problem is that when I unhide it, it is blank. Just dead space, and I can't get anything on it.

Under the Firefox menu- bookmarks, there is a sub menu labeled "bookmarks toolbar" that includes all of the bookmarks that used to be on my old toolbar. However, this section does not exist in the bookmarks menu at the top right next to the home button, although the rest of my bookmarks that were not on the toolbar are in both locations.

I have tried dragging bookmarks to the toolbar from both menus and the "show all bookmarks" pop out window and it doesn't work. Also I have tried saving a new bookmark to the toolbar. It does show up under the subsection of the firefox menu, but not on the actual toolbar (or in the bookmark menu)

• Show your blank Bookmarks Toolbar.
• Show the Menu Bar. This should show all your old toolbar bookmarks, yes?
• Turn on "Customize".
• In the Menu Bar, you will see now an icon followed by the text "Bookmarks Toolbar Items >>". Grab that and pull it down onto the blank Bookmarks Toolbar.
• Hit "Done" in the "Customize Toolbar" window.
• Send me a Scotch.

That did it! Thanks!

I had forgotten that in the old firefox, I had used "customize" to move all of the bookmarks from the actual bookmark toolbar to the empty space in the menu bar and then hid the now empty bookmark toolbar. In short, they were right where I left them.

Thanks again!
