Tab Loading Checker 作者： SexyWerewolf

Tab Loading Checker is a simple and effective Firefox extension that helps you keep track of your tabs' loading statuses at a glance. The extension's icon in the toolbar changes based on whether any of your open tabs are still loading. If all tabs have finished loading, the icon will turn green, indicating that your browsing is ready. If any tab is still loading, the icon will display an animated loading GIF, alerting you that content is still being loaded in the background. It's a handy tool for users who like to manage multiple tabs and want to know when all tabs have fully loaded without needing to check each one individually.
