Refined GitHub Notifications — Chrome Extension

A Chrome MV3 extension converted from antfu's userscript.

Enhances the GitHub Notifications page, making it more productive and less noisy.

Installation

1. Unzip this folder somewhere permanent on your machine
2. Open Chrome and go to chrome://extensions/
3. Enable Developer mode (toggle in the top-right)
4. Click Load unpacked and select this folder
5. Navigate to github.com/notifications — it's active!

Configuration

Click the extension icon in Chrome's toolbar while on any github.com page to toggle options:

• Auto mark done — automatically marks irrelevant notifications as done
• Hide checkbox — hides the selection checkboxes
• Hide issue number — hides #123 from notification titles
• Hide empty inbox image — hides the illustration on zero-inbox
• Enhance notification shelf — adds a FAB button to mark done & close tab
• Detail Preview — hover to preview issue/PR body (needs GitHub token for rate limits)
• Reactions Preview — shows reaction counts on notifications

You can also set a GitHub Token in the popup for the Detail/Reactions Preview features.

What it does

• Opens notifications in named tabs (reuses same tab per issue)
• Auto-refreshes when you switch back to the notifications tab
• Deduplicates notification tabs via BroadcastChannel
• Colorizes notification types (mention=green, review request=purple, etc.)
• Auto-marks done: closed/merged issues you've already read, Renovate/Dependabot PRs, cancelled CI runs, new commits pushed to PRs
• Removes bot avatars from the notification list
• Hides the blue unread dot on the notification bell
• Adds a floating "Done" button on issue/PR pages (Alt+X shortcut)
