I’m using Mac High Sierra on Chrome, and after years of using Metamask without any problem, a few days ago the dropdown went blank and its stayed that way ever since. I can see all my coins in dropdown menu if I switch to Firefox browser, so everything is still there, the menu just isn’t working in Chrome (latest version), nor is Uniswap, it also stays blank. I prefer to use Chrome, since it lets me adjust the gas fee. How can this be fixed?
Welcome to the MetaMask Community @markyugen!! 
Can you please specify what you mean by “dropdown”?
We’ve recently released an update to the extension. Please update your extension to the latest version and please try again.
Was this issue resolved? I am having the same problem on my Firefox browser. When I clock on the Metamask icon on the browser, I only see a blank page, instead of the account info and assets in the wallet
@kiaurash You have metamask seed phrase? When yes 
reinstall metamask wallet.
is this the same issue with me not being able to excess Smart Chain? I had it initially but for some time now it has been greyed out. keeping me from seeing my BnB.
