User Agent: Chrome / Mozilla/5.0 (Macintosh; Intel Mac OS X 10_10_2) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/40.0.2214.38 Safari/537.36") Build ID: 20150122030202 Steps to reproduce: Tried to clear the whole local storage in Firefox, including both DOM storage and IndexedDB. Actual results: There is currently no way to explicitly clear local storage in Firefox clearly exposed in the GUI, according to https://developer.mozilla.org/en-US/docs/Web/Guide/API/DOM/Storage#localStorage the only available workaround is to clear cookies via "Tools -> Clear Recent History -> Cookies" when Time range is "Everything" (via nsICookieManager::removeAll) but not when another time range is specified (quoted from the link above). I'm not sure that also includes IndexedDB. Expected results: Firefox should have a way of properly handling local storage, clearly exposed in the interface and giving the user the ability to clear all storage databases (DOM storage and IndexedDB) not unlike traditional cookies. As the IndexedDB is virtually unlimited database as stated here: https://developer.mozilla.org/en-US/docs/Web/API/IndexedDB_API "Firefox has no limit on the IndexedDB database's size. The user interface will just ask permission for storing blobs bigger than 50 MB." it is unacceptable, privacy and security-wise, that such a vast storage method may be out of the users's control and basically hidden inside the profile folder.

Thanks for the report! These are known issues: bug 527667, bug 1047098
