GitHub Bookmarked Issues by Richard Michael

Bookmark any issue from its page and find it later in one place. GitHub Bookmarked Issues adds a Bookmarked view to github.com/issues, alongside GitHub's built-in views.

Features:

• Bookmark button on every GitHub issue page
• Bookmarked view at github.com/issues with search, sort and filter
• Cross-device sync via your browser's built-in sync (Google Account or
  Firefox Account)
• Toolbar icon for quick access to all bookmarked issues
• Copy bookmarked issues as Markdown links
• Import issues from GitHub URLs
• Works without authentication; optional GitHub PAT for higher API rate limits

Permissions:

• Storage: saves your bookmarks and preferences
• Web Request: discovers GitHub API parameters for compatibility
• Host permissions (github.com, api.github.com): adds bookmark buttons to
  issue pages and fetches issue details from GitHub's API

No data is sent to any server other than GitHub's API. No analytics or
tracking. Fully open source.
