Ironically Vimium (and most extensions) are disabled on the Chrome Extensions domains. So when I hit 'yy' to copy the URL of the existing page it didn't copy it, so I instead pasted the last URL I had, which was the CPRA checklist. Not something I had intended to do, but I hope the checklist was useful.
