Good Morning all . Trying to connect Zilliqa [zillet wallet] and Theta [ thetaboard ] to my ledger nano s through ledger live ,which i have done for years successfully,on the same laptop as now but for a long time now i am getting this message :   U2F browser support is needed for ledger.please use chrome,opera or firefox with a U2F extension.Also make sure you're on an HTTPS connection. I need some guidance with the U2F ,as i got stuck with this before ; is this a chrome extension ?
                                                                                               Also, when i thought i would possibly access these wallets another way i.e, private keys / passwords i realised i don't have them .Therefor ,i can't remember ,as it's a long time ago did i , could i have set up the wallets by just connection to hardwear wallet option alone ?
                                                                             I would very much appreciate any help with this .
