Block 1Password on domains is a Chrome extension designed to enhance user experience by hiding the 1Password interface on selected websites. This tool is particularly useful for developers working in local environments who prefer not to be distracted by the 1Password UI while testing or developing. The extension operates by applying CSS to obscure the 1Password popup, ensuring that the password manager continues to function seamlessly in the background.

Users can easily manage domain visibility through a simple interface, allowing them to right-click or click the extension icon to either block or unblock specific domains. Once a domain is blocked and the page is refreshed, the 1Password UI will remain hidden, creating a more streamlined workflow. This extension is available for free and contributes to a more focused browsing experience.
