My bookmarks aren't available on my new computer. How do I get them back?

Question

My computer underwent re-imaging through my company MIS department. My IE bookmarks transferred and are available, my Chrome bookmarks transferred and are available, my Firefox bookmarks did NOT transfer and are NOT available. I need these bookmarks. We have copied my profile, but the bookmarks are not coming back to Firefox. How do I get my bookmarks back?
I have an HP ProBook 6560b running Windows 7 Enterprise.

Answer 1

Were all of the Firefox files copied to the new system?
Type '''about:support''' in the address bar and press enter.
Under the page logo on the left side you will see '''Application Basics.'''
Under this find '''Profile Folder.''' To it’s right press the button
'''Show Folder.''' This will open your file browser to the current
Firefox profile. Now '''Close Firefox.'''
Enter the '''bookmarkbackups''' folder. This is where Firefox makes backups
of your bookmarks. Look for the '''jsonlz4''' file you want to restore
(check the time / date / size). Right click on that file and select '''Copy.'''
Now go back to the profile folder where you started. Rename the file
'''places.sqlite''' by adding '''.old''' to it. Now right click in the folder
and select '''Paste.''' The file you just pasted here, rename it to
'''places.sqlite.''' After you are done, restart Firefox.
