Hi sonnyboy1, If your old computer motherboard died and NOT THE HARD DRIVE, your firefox profile is probably recoverable from that drive. If you do not know how to remove the old drive and connect it to your new computer, there are many computer shops that can recover the data from the old drive and give you copies, for a fee. You would need to recover your old Firefox profile and copy it to the new profile location on the new computer after you install firefox, and then tell Firefox where to find it. Of course, in the process of obtaining the data from your old hard drove, you could copy many other user files to your new drive, like photos, music, videos, spreadsheets, etc. If you also use Thunderbird as your email client, you could also use your old TB profile to recover your emails, etc. More information is in this article - [[Recovering important data from an old profile|Recovering important data from an old profile]]
