Form grabber and keylogger is pointless when you have lastpass grid or google authentication enabled on your lastpass account.
Say like, even if your pw is snatched, and lastpass grid is enabled, there is no way for them to get into you LP account unless they print off your grid from your house or screen capture the grid the first time you use it. You can have grid to be used on "your" pc once or all the time "recommend once". You can set remember this computer etc.
By far this is one of the badass option lastpass has.
