Features & Capabilities

WhatsApp in Sidebar is a Firefox extension that integrates WhatsApp Web directly into your browser's sidebar, allowing you to stay connected without switching tabs. It features a customizable keyboard shortcut (default Alt+Shift+W) and a convenient toggle button to open or close the sidebar quickly.

While Firefox restricts sidebar width by default, the extension's developer provides a detailed guide for unlocking and customizing this to maximize your WhatsApp viewing area. This add-on is an independent project designed for personal use and is not affiliated with WhatsApp or Meta. It leverages clean and intuitive iconography from UXWing for a polished user interface experience.

User Reviews

Users find WhatsApp in Sidebar functional and convenient, keeping WhatsApp accessible in a Firefox sidebar. Major drawbacks include repeated reloads on close, login requirements with no background notifications, and occasional white-screen/login problems, plus some size/overlay limitations. Overall, it shows promise—especially for Opera-like use—but stability and background behavior need improvement.

Pros

Very convenient to have WhatsApp open in the corner for quick access.
Useful and helpful for users migrating from Opera to Firefox.
Generally positive and functional experience.

Cons

Reloads/restarts whenever the sidebar is closed or the icon is clicked.
Requires logging in every time and offers no background notifications when closed.
Occasional white screen or login issues preventing use.
Not fully functional: limitations reading or replying to messages; sizing/overlay issues.
Sidebar size/overlay limitations causing content movement.

Is WhatsApp in Sidebar 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.

WhatsApp in Sidebar does not require any sensitive permissions.

Risk impact analysis details

Low This permission has no access or impact on the user's system or data, thus carrying no risk.

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.

WhatsApp in Sidebar has earned a fairly good reputation and likely can be trusted.
