Predefined Firefox Keywords are not Working

[Johnnymushio]

I'm sure you have noticed that instead of typing in youtube.com or going to google and typing in "mccain sucks", you can just type in "you" or "google mccain sucks" into the "awesome bar",and it will take you to the page. for the past two days, i have been very frustrated, because when i type in you, yahoo answers, or scooby doo into the awesomebar, it turns up with a search page frommy IP, not the site i wanna go to. is this just me? for example, type in "my" into the bar, and it should take you to myspace. but as for me, it doesnt anymore. why is this? is it just me?

edit

it appears to be a problem with me only. has it been turned off some how?

this page describes how to turn it off, so i checked and it is indeed all set to true. im stumped . and very annoyed. it happened all of the sudden, and i recall it happening maybe a year ago
