This post should really just read: JQuery 1.4 breaks(Refused to execute inline script) when used in Chrome Extensions using the version 2 Manifest. Update to Jquery 1.7 and you’ll be happy. Unfortunately it doesn’t, it reads more like: Last night I decided to cross something off my to do list and updated Foxish(a chrome extension) to use the version 2 manifest that will become manditory in a short while. For the most part it was pretty painless.
