Suddenly no access from account

[Matzkos]

Today i suddenly received this popup when connecting to polkadot:

One or more extensions are detected in your browser, however no accounts has been injected.

Ensure that the extension has accounts, some accounts are visible globally and available for this chain and that you gave the application permission to access accounts from the extension to use them.

Since some extensions, such as the polkadot-js extension, protects you against all community reported phishing sites, there are valid reasons to use them for additional protection, even if you are not storing accounts in it.

How to get access to my account again?

At the top of your extension do you see "Connected"? If so click it and connect your accounts.
