@jmort253 Okay, so in the first box, I need to put 9121977, and the second one needs to have https://stackexchange.com/users/1921977/jamestheawesomedude?‌​tab=inbox, right? Or do I need to put http://stackexchange.com/users/1921977/?tab=inbox?

@RobW Thanks! (I definitely didn't think it was trivial. ;)

Hey, I don't know whether it's turned on or not. Can somebody reply to this comment, so I can see if it's working?

@RobW Oh, wait. I poked around for a bit, then managed to find an XPI file. (THAT, I knew what to do with.) The configuration windows appeared for a minute, but I can't seem to make it come back.

@RobW Ummmmm.... what file am I supposed to download? I have never done this before, and there are no good instructions anywhere. Am I supposed to download all the files to the same folder, then change to that folder, and run the command? Am I supposed to find a "Download as .zip" link, and then run the command on that? What do I do?

@RobW Awesome! I'll be a beta tester and help you out with bugs! Thank you so much! I will tell you if I ever manage to get it built... (I hate building code from source. It's hard, buggy, and almost never succeeds.) I will give it a shot, though.

@jmort253 Oh, man. I wish that I were better at JavaScript. I understood what you said, but I haven't gotten into AJAX yet... I also don't know how to make a Firefox extension... But I understood what you were saying...

@jmort253 Ah-ha, I was originally misunderstanding the purpose of this add-on. Thank you for pointing me in the right direction.
