Restoring Firefox data from a computer that crashed

more options

My old computer crashed but I have access to the entire hard drive on my new laptop. I'd like to restore Firefox on the new laptop exactly as it was on the old laptop (bookmarks, tabs, etc.). All of the help articles talk about restoring from a backup, but I never made a backup since I obviously didn't know my computer was going to crash. Which files do I need to access from old hard drive and move to my new hard drive so that everything looks the same as before? Any help would be appreciated.

While i use different methodologies, your proposed methodology should work.

you would have to initially install FF on the o.s. so all the files will be registered by the Win registry.

then from there you can transfer the FF users files via differing methodologies:

So FF is installed and working on the new computer, but which user files (or folders) do I transfer from the old hard drive and where should I put them? The thread noted above doesn't offer any solutions on that. I can see a bunch of files in the "profiles" folders of both the new laptop and the old hard drive. Do I literally just replace the entire new folder with the old one? Thanks.

Copying all of the files in the profile folder worked like a charm! Thank you.
