Copy All URLs, Tab Exporter & Duplicate Closer

Copy all open tab URLs as Plain Text, Markdown, CSV, or JSON in 1 click. Batch open URLs and close duplicate tabs instantly.

Copy All URLs, Tab Exporter & Duplicate Closer is a fast, zero-quota Manifest V3 tab management utility for researchers, developers, and power users. Why switch to this modern Tab URL Exporter? Many legacy "Copy All URLs" extensions fail when you have more than 45 tabs open due to Chrome's 8KB sync storage quota or deprecated clipboard APIs. This extension operates directly in local memory with zero storage limits—even with 200+ open tabs. Key Features: • 1-Click Multi-Format Clipboard Copy: Instantly copy all open tabs in your current window (or across all windows) as Plain URLs, Markdown links `- [Title](url)` for Notion/Obsidian, or structured JSON. • 1-Click CSV File Download: Export a clean spreadsheet containing Tab Title, URL, and Domain. • Instant Duplicate Tab Closer: Automatically detects identical URLs open in multiple tabs and closes redundant duplicates in one click. • Batch Paste & Open URLs: Paste any text or list of links into the preview box to open all URLs in new tabs simultaneously. • 100% Local & Private: Uses only the minimal "tabs" permission. Zero host permissions, zero background tracking, zero external servers.
