IAM shouldn't be the only tab with a unique favicon! This sets favicons for many AWS services, so your tabs make more sense.
This extension sets the correct favicon for a bunch of AWS services, so it's easier to see at a glance what all your tabs are for. Over 100 favicons are included, with more on the way! And it doesn't read your browsing history (like some other favicon extensions). A note: This specific version of my extension will only work on AWS in China (amazonaws.cn). And because I can't create an account there, there's no way for me to test this but it's an exact copy of https://chrome.google.com/webstore/detail/aws-favicon-update/ohloajnmmkniehhbmjakbejnomonmijc so hopefully it will work well.
