I mean, I like Firefox, but dear God but I want this:
Google’s Chrome browser might soon be getting an easy way to tell you which open tabs are making noise, or recording it. The new feature is part of the latest Chromium build, and features a throbbing EQ animation over the noisy tab’s favicon (video below) to tell you and your system that it’s doing audio stuff. Chromium is the open source project that feeds into Google’s Chrome browser, and is often the first place that its new features show up.
Via Instapundit. I don’t know why this isn’t built into every browser anyway, honestly.
