Lost bookmarks and tabs after upgrade to Firefox 12
Against my better judgment I upgraded to Firefox 12. Immediately all the bookmarks were gone. Every time I started Firefox, I got a "New Tab" with nothing else. No bookmarks. No remembering of the previous tabs. I did a restore and thought I had fixed it since everything came back, however once I shut down Firefox and started it again it was back to the blank Firefox with nothing and "New Tab". I was previously on Firefox 10 and very reluctantly ever upgrade, but I had updated another computer to version 12 with no issues so I said "what the heck, worked once should work again." Wrong. Unfortunately this is my main computer. Please help.
Chosen solution
A possible cause is a problem with the file places.sqlite that stores the bookmarks and the history.

I fixed it by following cor-el's advice below. Make sure to check View->Toolbars->Bookmarks Toolbar when you restart Firefox after doing the solution below.
Thanks cor-el.
If a places.sqlite.corrupt file exists
If your Firefox profile folder includes a "places.sqlite.corrupt" file, one reported fix is to open the Firefox profile folder and, after closing Firefox completely, delete or rename the places.sqlite file and then rename "places.sqlite.corrupt" to "places.sqlite". (If you see any other places.sqlite* files, delete those as well, so that only one places.sqlite file remains.) It is possible that certain security or "cleanup" software (e.g., CCleaner) is causing the places.sqlite file corruption. It is also possible that Firefox was not closed properly, as might happen when your computer loses power with Firefox running, which can cause a corrupt places.sqlite file. Always make sure that you close Firefox properly (e.g., no Firefox processes in the Windows Task Manager) before shutting down the computer. [9]
I had this problem; don't know if it was the same cause but uninstalling the "BlackSheep" extension resolved it for me.
