If you work with Azure Storage accounts, you may already know the Azure Storage Explorer utility you can install on your client (Windows or MacOS) as well as it equivalent from the Azure portal.
Well, the Storage Explorer experience from the portal has changed and is now called Storage browser and provides a simplified storage explorer experience.
It allows you to set Favorites to quickly access your frequent storage content, a recently viewed list of resource and even let you start the Azure Storage Explorer utility if installed on your device.
You can access the new Storage browser experience by connecting to your Azure portal and access the Storage browser blade from the storage account you want to visit
If you want to add a resource as favorite, just browse to it and select Add to favorite from the contextual menu
