We have big blind spot in password manager usage as we don't know when users are using a saved login other than via about:logins (copy/reveal) and autofill on page load (which doesn't mean the user actually submitted the form). We currently only know when a login is autofilled, saved or updated. Bug 1621520 will record filling via the context menu and autocomplete but that doesn't necessarily mean the saved login was submitted afterwards.

We do have [PWMGR_LOGIN_LAST_USED_DAYS](https://probes.telemetry.mozilla.org/?search=pwmgr_&view=detail&probeId=histogram%2FPWMGR_LOGIN_LAST_USED_DAYS) but it's includes all logins put into buckets so can't easily tell you whether the user used any saved logins in a session.
