It seems to work okay, I'm only 1-month into the NFT-scene (the only thing causing me to mess with Crypto at all). It works okay w/ Firefox, but I always seem to have to login and then open a new tab. I can't just goto the Market and have my account/wallet show up. But yeah when in doubt just restart the browser. I just sold my first NFT for $50 on Voice (which is cash) so I'm not sure if I still need to use my wallet or if they use a real bank account so I haven't withdrawn any Crypto>Cash out yet. But I'm going to just to say I have. But I plan on putting some Cash>Crypto (ETH) so I can make my 2nd & 3rd Collection Launches much more professional. I'm an Artist, I really could use a small 3-4 person Team to Develop/Launch/Market a medium/large Collection but hey, I'm doing my best and MetaMask has never pulled any glitchy BS on me yet, but I've had no money for it to. So I'm giving it 3/5 and will re-review AFTER dealing with money withdraws and deposits.
