Ever get the nagging feeling that a Chrome web app or add-on isn't entirely above board? You now have an easy way to prove it. Google has posted a new version of a Chrome developer tool that lets you see just what your apps and extensions are up to. While it's meant for programmers, it should be helpful if you're simply concerned about privacy or security; if a weather app is inexplicably changing pages or sifting through your history, that may be your cue to uninstall it. The tool isn't all that vital now that Google is starting to cut off extensions that don't come from the Chrome Web Store, but one additional safety net won't hurt.
