Mozilla's latest version of Firefox addresses a critical security flaw that was recently discovered at the 2010 Pwn2Own contest by security researcher Nils of MWR InfoSecurity. The flaw, which existed only in version 3.6 and later, was related to memory corruption via "re-use of a freed object due to scope confusion," and could have led to an attacker running arbitrary code on a victim's computer.

Untrash the Trash
Feeling trasher's remorse? On Snow Leopard, you can open the Trash (click the Trash icon in the Dock) and "untrash" individual items there. Select one or more trashed items (files and folders) and choose File > Put Back. This returns the items to where they were when you originally put them in the trash. The keyboard shortcut is Command-Delete - the same as the shortcut for trashing an item in the first place, since in deleting something from the trash you are untrashing it.
