Features & Capabilities

Gmail Sender Icons is a Firefox extension that makes it easy for you to quickly and visually identify email senders in Gmail. It shows the company domain name 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 larry@google.com, the Gmail extension will add a virtual label google.com to your email message and also a logo of the Google website next to the message so you can immediately identify the sender in the email list.

Gmail Sender Icons has been featured on Product Hunt, LifeHacker, The Next Web and host of popular websites.

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 Firefox 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.

The add-on is open source and the code is available on Github.

Is Gmail Sender Icons Pro Safe?

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Gmail Sender Icons Pro requires a few sensitive permissions. Exercise caution before installing.

Risk likelihood

Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

Gmail Sender Icons Pro may not be trust-worthy. Avoid installing if possible unless you really trust this publisher.
