Flush Site Data
Adds button/hotkey to clear cookies, localStorage, indexedDB, cache, serviceWorkers, sessionStorage and pluginData for all sites and tabs
What is Flush Site Data?
Flush Site Data is a handy Firefox add-on that adds a button and hotkey to clear various tracking data stored by websites, such as cookies, localStorage, indexedDB, cache, serviceWorkers, sessionStorage, and pluginData. It provides a quick and efficient way to log out of all sites and tabs without any prompts or limitations.
Adds button/hotkey (default - Alt+C) to flush all cache, cookies, localStorage, sessionStorage, indexedDB, serviceWorkers and pluginData - i.e. all tracking stuff that sites store in browser.
Alternative to Ctrl + Shift + Delete firefox hotkey, but without prompting/checkboxes, and also clearing sessionStorage in all tabs.
It does not clear downloads/history, passwords and form autocomplete data that is (almost entirely) used in the browser UI, not by websites.
Does not ask any questions or limits its scope in any way. Useful to log out of everything, like closing/reopening private browser window. Issues notification on success, and does console.error() on any failure.
Flush Site Data is risky to use as it requires a number of sensitive permissions that can potentially harm your browser and steal your data. Exercise caution when installing this add-on. Review carefully before installing. We recommend that you only install Flush Site Data if you trust the publisher.
Flush Site Data has earned a fairly good reputation and likely can be trusted.
