Show sender favicons for Gmail messages
Gmail Sender Icons is a Google Chrome extension that makes it easy for you to identify the email sender in Gmail. It show the company domain of the email sender and the official logo (favicon) of the sender's organization alongside the email message. For instance, if you receive an email from firstname.lastname@example.org, the Gmail extension will add a virutal label google.com to your email message and also a logo of the Google website.

The favicons and the sender's domain are visible across Gmail including search results. The sender's label is applied virtually and the actual labels of the email message are left unchanged.
The Gmail Chrome extension uses the Google S2 service for generating the website's favicon while the Gmail messages are parsed with the Inbox SDK framework. All processing is done locally in your browser and no Gmail data is ever shared or uploaded anywhere.
