The Windows Reset typically gives you options for whether/where to save your data. Typically that would be in a folder named:

C:\Windows.old

If you find that folder:

Set Windows to show hidden files and folders -- this Microsoft article has the steps:

Then explore that folder up to this point (if it exists):

C:\Windows.old\Users\<username>\AppData\Roaming\Mozilla\Firefox\Profiles\

If you find recent data there, please pause and we can suggest how to resurrect your saved files.
