I have a Ledger Nano S crypto wallet. Not all cryptos show directly in my Ledger and I wish to use MetaMask to view them. When using Chrome, with my Ledger connected and active, my Ledger doesn't connect due to "unknown error". When using Firefox, with my Ledger connected and active, my Ledger similarly doesn't connect due to "unknown error" although in this case there was an additional screen note from Firefox regarding "ongoing problems connecting Ledger devices to MetaMask (origin April 23?)". When using Brave browser there is not a problem viewing my tokens (although a different problem is that I lose token upgrade functionality - hence my desire to connect Ledger to MetaMask using a different browser - preferably Firefox). I use the latest versions of the browsers and Windows 10 in conjunction with Avast One anti-virus. I’ve also cleared cookies and cache several times. All drivers and software are up to date. Any thoughts on rectifying my connection problem please?
