Features & Capabilities

Yahoo! Mail Notifier is a lightweight Chrome extension designed to provide instant alerts when new emails arrive in your Yahoo! Mail inbox. Unlike other add-ons that load entire webpages, this notifier fetches only minimal data (in kilobytes), making it fast and efficient, saving both bandwidth and time.

To use this extension, ensure you are logged into your Yahoo! account. Additionally, if you enable the "Show mail preview popup" setting, you can conveniently open Yahoo! Mail in a new tab by middle-clicking the toolbar icon. This extension enhances your email checking experience by keeping you promptly informed without unnecessary delays or data consumption.

Download it from the Chrome Web Store and enjoy seamless Yahoo! Mail notifications.

User Reviews

Users praise the add-on for reliably notifying new mail, showing unread counts (including linked accounts) and providing quick access. Several reviews also note the developer keeps it updated. The main recurring problem is a connection/login error marked by a '?' icon (and some dislike the '?' indicator vs the previous 'x').

Pros

Reliably notifies you of new Yahoo Mail so you don't have to check manually.
Can monitor specific folders/inboxes and shows unread counts (including other accounts connected to Yahoo).
Simple quick-access button/icon for opening mail; lightweight and easy to use.
Actively maintained — users note updates and fixes from the developer.

Cons

Occasional login/connection problems: icon changes to a '?' and reports not logged in (stops working) — mentioned by multiple users.
The notifier icon/state can be confusing (some users preferred the previous 'x' indicator over the '?' error symbol).

Great! Does exactly what it sounds like. You have to log into Yahoo Mail in the browser, then you can close the tab and the addon will notify you when you get email. You can choose which inbox/folders to monitor, I have it only check the main Inbox.

Is Yahoo! Mail Notifier 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.

Yahoo! Mail Notifier requires some sensitive permissions that could impact your browser and data security. 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.
