Wide GitHub is a browser extension that makes GitHub’s layout wide, enhancing readability, reducing vertical scrolling, and improving accessibility.

It works on GitHub, private Gists, GitHub Enterprise, and custom TLDs (Firefox 109+ and Chrome Manifest V3 supported).

• Makes GitHub's layout wide and accessible.
• Supports custom domains (e.g. GitHub Enterprise).
• Toggle on/off with a single click.
• Syncs settings across devices (Firefox Sync / Chrome Sync).
• Handles SPA navigation and tab switches.
• Easy preferences and URLs management via settings popup.

1. Visit Wide GitHub for Firefox
2. Click "Add to Firefox"
3. Confirm the installation

1. Visit Wide GitHub for Chrome
2. Click "Add to Chrome"
3. Confirm the installation

1. Click the extension icon in your browser's toolbar
2. Toggle the switch to enable/disable the wide layout
3. Add custom domains in the popup if needed

You can add custom domains where you want the wide layout to be applied:

1. Click the extension icon
2. Enter the domain in the input field (e.g., git.mycompany.com)
3. Click "Add" or press Enter

The extension will automatically handle:

• Subdomains (e.g., docs.github.com)
• WWW redirects (e.g., www.github.com)
• Protocol changes (http/https)

All source code is in the src/ folder and is shared between Chrome and Firefox builds.
Manifest files are separate for each browser.

If you just cloned the repository, make the build scripts executable:

chmod +x build.sh package.sh

To build the extension for both browsers:

./build.sh

This will generate the folders dist/firefox and dist/chrome with the ready-to-use extension files.

To create ZIP files for release (excluding system and dev files):

./package.sh

This will create wide-github-firefox.zip and wide-github-chrome.zip in the project root, ready for upload to the stores.
