Clear/reset cookies?

[atom-smasher]

Playing around with a popular mapping web-app, I'd like to request a feature to manually clear/reset identifying cookies and such, on a per app basis.

For most web-apps (email, social media), maintaining a persistent login is desirable. For mapping, even without a login, cookies and other non-persistent identifiers may not be desirable.

If this is implemented, it may or may not be desirable to do that automatically when the User Agent is changed. That might be best suited as a per-app option.

Thanks.
