Old Fashioned Way
You should be able to do that the "old fashioned way".
- Select the Profiles folder (inside C:\Users\<User Name>\AppData\Roaming\Mozilla\Firefox\Profiles)
- Copy it to your backup location

I noticed something interesting on my PC.
I have multiple profiles (only one is in the default location, the others are on another partition).
Only the profile in the default location has a folder inside C:\Users\<User Name>\AppData\Local\Mozilla\Firefox\Profiles
If I create a new profile:
- In the default location, a folder is also created in ... AppData\Local\ ...
- In another location, a folder isn't also created in ... AppData\Local\ ...

Another way to reset Firefox
Another way to reset Firefox is to use the Profile Manager.1 - Open the Start MenuWhen you restart Firefox, it will create a new profile and you should see the window that asks you, if you wish to import data from Internet Explorer.
2 - Type "firefox.exe -P" (in the Search box, without quotes, remember the space)3 - In the Profile Manager ("Firefox - Choose User Profile" window), select the "default" profile
4 - Click on the "Delete Profile" button5 - In the "Delete Files" window, choose "Delete Files" to purge ALL existing user files.
6 - In the Profile Manager, click on the "Exit" button

Yet another way to reset Firefox
You can also type "about:support" (in the Address bar) to see more information (like config changes).
You can reset Firefox from that page.You'll need to click the picture several times to see it at full size. :)
