v5.12.5431
win xp
i'm on an old system so maybe this has been fixed.
go to: tools > startup > google chrome tab
4 plugins are showing up that are no longer in use or even on my computer.
i think what happened is that i was dealing with a really stubborn piece of software (RealPlayer and RealJukebox - avoid if possible) that just would not uninstall itself completely; it left traces all over the place.
i got fed up with standard ways of trying to get rid of it and at one point i'm pretty sure i went into the Application Data folders and manually deleted everything i could find related to RealPlayer and RealJukebox. but CCleaner seems to think the plugins are still there. i'm quite sure there's no trace of them left, but i could be wrong. i did find some traces in the registry but i'm not sure if those are relevant.
also, these plugins don't show up in other browser tabs (in ccleaner). doubly weird because i don't think i ever used the plugins while in chrome.
