Twitter on Thursday warned of an esoteric bug that, in limited circumstances, allowed users’ non-public profile information to potentially fall into the hands of other users.
If you used Firefox on a shared PC to, for example, send or receive media in private Twitter messages, or download an archive of your profile that contained non-public information, be aware this data was inadvertently cached on the computer.
