Add-on summary

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.
