total-tabs-exporter 作者： Aman gupta

Export all your Firefox tabs to Markdown, JSON, HTML, or plain text in one click.
Supports native tab groups (Firefox 140+), containers, 1000+ tabs, current tab and clipboard copy.
Useful for backing up your browsing sessions, sharing tab collections, or organizing research. Made this because I couldn't find any on firefox that can export "groups".
