I don't update this anymore because I don't use it. Sorry everybody. :'(
Always inject jQuery into every page without clobbering any existing libraries.
The latest v1 release of jQuery is injected into the page from Google CDNs. If $ or jQuery are already defined on the page, they aren't broken. A badge on the app icon shows the variable name by which the injected jQuery can be accessed in the console.
