I can't find my old Firefox profile after a data reinstall.

I recently had my computer data removed and reinstalled. Now I can't find my old Firefox profile. Is there any way to locate it?

I have a Toshiba Satellite with Windows 10. I had to reinstall Firefox after getting my computer back, but all I can find is the profile for my new browser, not for any of the past ones. All my data was supposedly saved. Would by bookmarks and cookies be located anywhere else?

Everything was in the proper location except for the programs, which were deleted. I do have to reinstall those.

I was not talking about the system files, I was talking about all the other file and data that were on the hard drive before the cleaning.

If you mean in general, from what I can that appears to be intact. If you are talking about Firefox, I have yet to find the old profiles and their data on my hard drive.

The links I posted did not help you find the profiles folder?

Hi jesaray, Firefox data is stored under:

C:\Users\your-user-name\AppData\Roaming\Mozilla\Firefox\Profiles

In order to explore that path and see what you have there, you need to set Windows to show hidden files and folders:

Do you have any old data there?

If not there, can you find where they put old data from your user profile folder? A standard Windows 10 refresh moves the data under:

C:\Windows.old

so it would be

C:\Windows.old\Users\your-user-name\AppData\Roaming\Mozilla\Firefox\Profiles
