Can you recover lists of my passwords from firefox after my computer was purged from viruses?

My desktop computer was infected with malware when I was called by a man supposedly from Paypal stating that I has been erroneously charged with over $600 of merchandise and he wanted to get information to refund the money to me. I gave him information (sadly) to enter my computer outfitted with Firefox running on Windows 11. After consulting my bank, they said that there was no way for Paypal to refund the money as he wished to do. Apparently he was infecting my computer while we spoke. I realized that is was a scam shortly after I hung up and shut the computer off. The next morning I took it to our local tech center and they 'cleaned' it. Now I find all of my passwords stored in Firefox are gone. Do you have a way of recovering them?
