So I have just upgraded to Firefox 4, and discovered that LJLogin is not compatible with it. Cue the cries of NOOOOOOOO. However, I do remember that someone made a Chrome-like login add-on, and if anyone knows what that is and/or where I can download it (or a new LJLogin-type add-on for Firefox), I'd really appreciate it. Even though Firefox still remembers all of my account passwords, I hate having to log out of each account and log into another one without the ease of pushing a button.

Question, what do you all (if any of you do) use as far as icon randomizers? I tried LJ-Hook a while back and couldn't figure out how to use it so if that's my only option, a quick explanation of how to get it to actually randomize my icons would be great.
