The Chrome Version of this extension is superior to the firefox one because of its ledger support. In firefox you are not able to connect your ledger via Binance Chain. If you choose Binance smart chain you can connect your ledger, but only with your legacy address and not with your ledger live one. If you try it the window just closes itself and forgets what you tried to do. But in evry other aspect a solid plugin. Hope they fix it soon.
