Google Messages Web — Hide Sidebar

Name: Google Messages Web — Hide Sidebar
Author: David F Dev

Hide the conversation list on Google Messages Web with a single click. Replaces the always-on sidebar with a slim edge-attached toggle button, and remembers your last conversation so reloads don't drop you on the welcome screen.

Features & Capabilities

Google Messages Web — Hide Sidebar gives you back the full width of the chat window on messages.google.com/web/. The conversation list and Start chat button are hidden by default. A small drawer-handle button on the left edge of the viewport lets you bring the sidebar back at any time and tuck it away again when you're done.

Features

Hides the left sidebar: the conversation list and the Start chat header. The right-hand pane (your active conversation) gets the full width.
Slim toggle button: a 16-pixel pill on the left edge. Click to reveal the sidebar, click again to hide it. Stays out of the way of Google's own UI.
Remembers your last conversation: when you reload or reopen Google Messages, the addon takes you straight back to the last conversation you were viewing. No more landing on an empty welcome screen with the sidebar hidden.
Works inside Firefox Taskbar Tabs: the conversation-restore logic is tuned for Taskbar Tabs / site-windows.
Self-healing: if a stored conversation has been deleted, the addon detects the bounce and clears the stored id automatically.

Privacy This addon stores exactly one piece of data in browser.storage.local: the id of your most recently viewed conversation. That data lives on your device, is scoped to this addon, and is never transmitted anywhere. There is no network code in the addon at all.

Requirements Firefox 109 or later (Manifest V3).

Is Google Messages Web — Hide 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.

Google Messages Web — Hide Sidebar 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.
