Click and Clean от BrowserNative

One click to delete all your browsing data including all open windows, browsing history and caches, cookies, downloads history, form data, and other stored data. Use Ctrl + Alt + C keyboard shortcut.

By default, the Click and Clean deletes browsing history, saved cookies, downloads history, cached files, saved forms data, plug-ins’ data along with websites’ App Caches, local storage data, indexedDB, WebSQL and file systems data. It also closes all windows and tabs, and launches a new tab in a new window. But users can customize this behavior and select only few data items to be deleted.

To prevent accidental clicks from resulting in data deletion or loss, we have relocated the clear function—originally triggered by clicking the extension icon—to the Options page, where it can now only be executed by clicking the "Clear" button or by using a keyboard shortcut.
