I'm having a problem with the link to my gmail address in the AddThis toolbar. I don't know where to ask for help - is this a Firefox thing? Or something added by someone else (in which case I will just eliminate the whole toolbar..it's not that helpful anyhow if it's going to screw up. I just need to know if this is a Firefox deal, if so, I'll ask a more detailed question. Don't want to waste both of our times if AddThis is not part of Firefox...
