very good

Great wallet for Ergo and Cardano!!

Great UX and UI

Best crypto in the industry!

Best lightweight wallet for Cardano.
Hands down.

Yoroi is arguably one of the best digital assets wallets available. the user interface is a lightweight clean and intuitive. the wallet is supported by two different browsers chrome and Firefox at the present time. ( i.e. both are browser extensions)
 the wallet is highly secure in that it allows the user to take advantage of two different forms of cold storage.
 the two methods include the creation of a paper wallet or connections via a ledger nano S
 in the fall of the 2019, the Cardano project will introduce taking. as it will be a fully decentralized, proof of sake, block chain implementation.

 note there is one feature I really wish this law that would include. may be a configurable option?
 using the price Obtained from coin market API…… display the total amount owned of ADA in U$D. ( or a configurable unit amount?)

Emurgo's Cardano Wallet Yoroi for Firefox works flawlessly as expected. I've successfully linked my Ledger Nano S with no complications and got my balance instantly.
