Jarren said: I’m not sure about the ‘possible infinite loop detected’ issue, but the spacing of your scripts is simply a CSS issue on how they are being displayed. If you’d like a Stylus fix you can check out my post here . The thing that actually destroys the ordering is the height of the little glob icons, which are Pictos, with a higher font size than non-One Click script titles. You can make them line up better with a single line of Stylus CSS: .pictos {font-size: 12px !important; max-height: 14px} And yeah, without CSS monkeying., the whole ordering of the scripts looks terrible. As for the error, it would be nice if the Console told you the line number within a particular script, but they are all concatenated into one big uber-script at run time. Do you get any more info? If not, then the only thing to do is disable scripts until you find the culprit. The One-Clicks are probably the most stable, since they are more likely to be reported and are all using identical code.
