ChatGPT simple Widescreen Perry das Schnabeltierhen توسط

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.

• widens the visible ChatGPT conversation layout
• 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:

1. Open about:debugging
2. Select This Firefox
3. Click Load Temporary Add-on...
4. Choose manifest.json from this folder
5. 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.
