This is the source for the JsError extension for Google Chrome as available to install at https://chrome.google.com/webstore/detail/nnplccbllaclkbbmoldiamkhgohelbjh As you'll see, this is minimal extension but I've published the source so people can seea working extension with not much code, but a toolbar button, options, the manifest files etc I made the zip files for each version using the little mkzip one-liner and include them here as that's how you deploy projects to the Chrome Web Store The icons are sourced from the excellent http://code.google.com/p/ultimate-gnome/ and are used subject to the license there The icons in that project are made available under the GPLv2 license so I'm going to likewise say This work is published under a GPL v2 license There's so little code it might seem daft to consider the license, but I appreciate the effort newmooon has put into the icons so it's mostly to protect his work.
