Where userstyles are stored locally on the computer?

[TuTAH1]

I reinstalled browser and somewhy all userstyles are gone. Last userstyles backup was made a whole half year ago. But! Before reinstalling the browser, I made a backup of a whole browser folder (including User Data), so how can I get my userstyles from a backup?
