Firefox Opens when my computer starts up

[RosieO]

When I restart my iMac Firefox automatically opens. I don't want that. I just want to see my desktop. I can't find any setting to turn this off. Any ideas?

Click and hold on the FireFox icon in your dock. Then uncheck Open at Login.

Thank you for the quick reply. I knew it had to be something simple that I was missing!
