Forum:Site notice not being dismissed

This has probably been asked before but I can't find any topics that help me. I have recently switched from IE to Firefox and now, whenever the site notice is updated, it keeps on coming up even after I dismiss it. I imagine it's something to do with javascript or cookies, but I have both enabled already so I don't know what the problem is. Thanks in advance for any help.
