I'm having a problem transferring settings between profiles. The following procedure replicates the problem: Launch Firefox with an existing profile and reconfigure the navigation toolbar so that the Stop and Reload buttons are separate. Using Profile Manager, create a new profile; DON'T launch Firefox. Copy file localstore.rdf from the old profile to the new profile. Launch Firefox with the new profile and observe that the Stop and Reload buttons in the navigation toolbar are in their default, combined configuration. Close Firefox and copy file localstore.rdf from the old profile to the new profile AGAIN. Relaunch Firefox with the new profile and observe that the Stop and Reload buttons in the navigation toolbar are separate. The same thing happens with bookmarks menu tweaks and file places.sqlite (I'm referring to tweaks to the menu itself, not the bookmarks). It seems that Firefox doesn't honor some of the settings in localstore.rdf and places.sqlite the first time it is run with a new profile. Running Firefox the first time over-writes the custom settings, requiring that the files be copied a second time. Then it works as expected. I stumbled across this while trying to pre-install Firefox v9.0.1 and my custom settings on several systems running Windows XP.

Does anyone know a work-around?
