Ever tried to write a userstyle and couldn't find the right selector? Are nested objects with inherited class attributes too complex to dig out of the source code?

Yeah, me too.

Enable this handy little tool, and you can point at an object, view its class or ID attribute, and go about your business.

Just make sure you disable it when you're done viewing the class/ID structures, so you can go back to seeing the page normally.
