Features & Capabilities

ChatGPT Widescreen is a minimal Firefox extension that makes the ChatGPT interface use more horizontal space on widescreen displays.

The extension is intentionally simple and focused. It only injects a small CSS override on https://chatgpt.com/* to widen the visible chat area.

It does not add features, menus, or controls. It only alters some CSS on the site and nothing more.

This add-on was created by Arne, with support from ChatGPT.

applies automatically on https://chatgpt.com/*
uses only a local CSS override included in the add-on package

no JavaScript logic
no background script
no remote code
no telemetry or analytics
no data collection
no external network requests
no settings page
no preferences or options to change

The extension is active only on the following site:

https://chatgpt.com/*

It does not affect any other website.

The add-on package contains:

manifest.json
widescreen.css
icon files in icons/

Firefox loads the stylesheet through content_scripts, and the CSS is applied automatically when ChatGPT is opened.

This extension is designed to be minimal.

It does not read or transmit user data. It does not collect usage information. Its purpose is limited to applying CSS styling on ChatGPT pages matched by the manifest.

To test the extension locally:

Open about:debugging
Select This Firefox
Click Load Temporary Add-on...
Choose manifest.json from this folder
Reload any open ChatGPT tab

This version is structured for submission to Mozilla Add-ons.

Because Mozilla's built-in data-collection declaration used by this extension is supported from Firefox 140 on desktop and Firefox for Android 142, those are the declared minimum browser versions.

For permanent installation in normal Firefox Release, Mozilla signing is required.

Is ChatGPT simple Widescreen 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.

ChatGPT simple Widescreen 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.

ChatGPT simple Widescreen is recently added, and hasn't been around long enough for us to gather enough data to accurately assess its risk level.
