A cookie can hold a signed-in session. After cookies are cleared, those sites show a sign-in page again.
The cache is a copy the browser kept so pages could open faster. It is not the file browser, and it is not your photo library.
Open what to clear for the difference between one site, cookies, and cached files. Then open the page for the browser you have.
Menu labels vary by version and language. Each desktop page also lists an address that opens the settings screen. That address works only in that browser's address bar.
