About this extension
I was annoyed that I couldn't find an approved or open source version for this. So here is my solution. Please consider buying a coffee for me :)

Functionality:
The plugin scales the output of ChatGPT to 100% width. No matter if the sidebar is hidden or extended.
Works for free and paid version.

Source: https://github.com/JThyroff/WideGPT

Instructions to set a custom width:
  1. Locate the Extension Icon:
    In the Firefox toolbar, click the puzzle piece icon (🧩) on the right side of the address bar. This will open the extensions menu.
  2. Find "WideGPT" Extension:
    Look for "WideGPT" in the list of extensions.
  3. Open the Extension Settings:
    Click on the extension icon (the "W" symbol) to open the settings popup.
  4. Adjust the width and refresh ChatGPT!
