The history sidebar does not automatically come up when I start Firefox.
I always had the history sidebar set to appear when Firefox booted. Now I have to manually open it each time. Why?

Delete localstore.rdf or rename the file to localstore.rdf.sav in the Profile Folder to test if the file is corrupted.
See http://kb.mozillazine.org/Corrupt_localstore.rdf
(caution: do not delete the localstore.rdf file in the Firefox program installation folder)
Note:
Deleting the file localstore.rdf will reset the customizations of the toolbars to the defaults.
You can rename "localstore.rdf" to "localstore.rdf.sav" to test if that solves it.
Then you can restore the customization by copying "localstore.rdf.sav" to "localstore.rdf" if it didn't work.
I have the same problem. SOMETIMES (about 10% of the time) the Bookmarks sidebar does not appear when starting FF. This began after installing version 11. Any ideas?
