Info on where to find your profile folder, etc. from Firefox. I hope this helps. It is your profile you need to move from 1 PC to another IIRC.
"How To Manage Profiles
Mozilla Firefox stores all your personal settings, such as bookmarks, passwords and extensions, in a profile. The profile is stored on your hard drive in a profile folder.
If you run into problems using Firefox (e.g. problems starting after installing an extension, or other features not functioning properly), the first thing you're usually asked to do in the tech support forum is to create a new profile. This tutorial will show you how to do that.
Locate your profile folder
It's not required to know where your profile folder is located in order to create a new one. However, it's good to know it anyway, for example, if you want to make a backup of your settings.
On Windows XP/2000, the path is usually %AppData%\Mozilla\Firefox\Profiles\xxxxxxxx.default\, where xxxxxxxx is a random string of 3 characters. Just browse to C:\Documents and Settings\[User Name]\Application Data\Mozilla\Firefox\Profiles\ and the rest should be obvious.
On Windows 95/98/Me, the path is usually C:\WINDOWS\Application Data\Mozilla\Firefox\Profiles\xxxxxxxx.default\
On Linux, the path is usually ~/.mozilla/firefox/xxxxxxxx.default/
On Mac OS X, the path is usually ~/Library/Application Support/Firefox/Profiles/xxxxxxxx.default/
%AppData% is a shorthand for the Application Data path on Windows 2000/XP. To use it, click Start > Run..., enter %AppData% and press Enter. You will be taken to the "real" folder, which is normally C:\Documents and Settings\[User Name]\Application Data.
Create a new profile
In order to create a new profile, you use the Profile Manager. To start the Profile Manager, follow these steps:
1. Close Firefox completely (select File > Exit from the main menu of Firefox).
2. Select Start > Run... from the Windows Start menu.
3. Enter firefox.exe -profilemanager and press OK.
On other operating systems, start Firefox with the the -profilemanager switch, e.g. ./firefox -profilemanager (this assumes that you're in the firefox directory).
You should now see the Profile Manager window, shown in the screenshot to the right.
From the Profile Manager you are also able to remove and rename profiles.
Click on the Create Profile... button to start the Create Profile Wizard. Click Next and enter the name of the profile, e.g. your name or something descriptive.
You can also choose where on the disk you want the profile to be stored, which is useful if you plan on exporting your settings to another computer or setup in the future.
Finally, click Finish to have Firefox create the new profile.
You should now be taken back to the Profile Manager and the newly created profile should be listed. Select it and click Start Firefox. That's it!
You are now running Firefox with the new profile, which means all settings are reset to default. If you want to switch back to your old profile, just start the Profile Manager again (instructions above) and select the old profile.
You can also have Firefox start a selected profile automatically, so you don't have to pick one each time the browser is launched. Do this by checking the Don't ask at startup option."
