Migrated from FF 3.6 to 7.0 on OS X, lost History during migration

I recently did an update on a Mac Laptop, running Lion (10.7). The version of Firefox on it was 3.6 at the time, I installed 7.0 in its place. Two things happened:

1) The user had been saving all of her tabs upon quitting FF, using the dialogue box each time on close. When I upgraded her to FF7, it remembered all her tabs, then promptly forgot them when it next closed - the default action upon launching the App was to go to the FF home page, and not her tabs from the previous session. It never prompted me to remember / save them. Is there any way to recover this?

2) Her history is completely gone. I understand this was likely a result of the history file from 3.6 not being compatible with 7.0. Her bookmarks are fine, but the history is not... is there a way to recover this as well?

Thank you!

I should note I was smart enough to back up her laptop to an external drive, so I have a complete, accessible image of her old profile available, if the settings can be imported.

I was able to figure this out - I grabbed the Sessionsstore.js file off the backup, and also found the History was there when I checked back a second time. We're all good.
