Had to restore Windows, can I get old bookmarks from "Mozilla" folder copied before the restore?

I had to do a Windows System restore on my computer. I had to manually back up all my data files (thanks to my computer freezing when I tried to do the backup as part of system restore). I copied all items in my Program Files (x86) folder, including Mozilla. Is there any way to recover my Firefox bookmarks? I had TONS of bookmarks in about 20 different folders. In the past (maybe 3 years ago), Firefox used to lose my bookmarks a lot so I've spent hours restoring, or starting all over again. This time, I am hoping I don't have to do all that - much more work since it's about 2.5 years worth of bookmarks! Argh! Thank you.
