For some reason searches using Firefox Google pull up Canadian sites instead of my actual location. I've tried changing settings in Google and Firefox but no matter what it keeps defaulting to Canada.

Do you live on or near the Canadian border? Thats probably Google's location service which kinda stinks at times. I live in Reno but companies like Walgreens think I live in Sacramento, Ca. Google is not part of Firefox. There has to be a reason for this but its beyond me - I know GPS is accurate.
