I have this problem too, using Linux Mint with Firefox 12 and only Firebug installed. I have the `en_CA.UTF-8` locale.

Some testing with a range of dates shows that the toLocaleDateString() method is showing all dates in YY-MM-YYYY format. Other date formating methods: toDateStriing, toLocaleString, toUTCString give correct results. *probably* this is a problem with the default locale settings, but I do not know how to find out what 'package' that is, or how to use an alternate path (outside firefox) to verify that. All of the other ubuntu date text that I can 'see' are correct, but [from formatting] appear to be using one of the other locale specific methods and formats To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/firefox/+bug/752007/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
