At last! The latest version of Google’s Chrome Web browser has added tab icons to notify you if a tab is playing audio, accessing your microphone, or being cast to a Google Chromecast. The new audio alert icon should make it easier to find and silence annoying autoplay videos, such as on sites like -cough- Macworld. The other interesting addition is a preview of the new supervised users mode (ideal for young children), which lets you see a user’s browsing history and restrict access on a per-site basis. follow link
