This is one of the 2 official wallets from the Cardano blockchain. Daedalus is a full node wallet built by IOHK demanding alot of resources from your computer, while Yoroi is a light wallet built by Emurgo. (IOHK, EMURGO and Cardano Foundation are the 3 official entities which created Cardano).

I can say that after some major upgrades on the Cardano network there were some issues in the functionality but the team usually have done their best to fix them. There is never a concern of loosing the funds but just about not being able to do certain tasks. Yet, when there is something wrong you can always swich and restore your crypto assets on another wallet like Daedalus or even Adalite.io and use them there until Yoroi is fixed.

It is available on mobile and it can be used as an add-on on Firefox, Chrome and Edge. I also use it paired with a Trezor model T.

I'm using it by a few years and I really like it.

Just installed this add on in Firefox and it went relatively well. The interface is quite intuitive and clean. I was able to pair my Trezor Model T hardware wallet to it easily. Now I'm waiting for a small test transaction of Cardano ADA to complete to verify its functionality. If all goes well, my opinion of the Yoroi wallet will be enhanced.

I'm updating my review as the extension was fixed. Thanks
