DDB Cobalt Copier grabs the D&D Beyond CobaltSession cookie with one click and puts it on your clipboard so you can authenticate third‑party tools without digging through dev tools. The extension lives in a compact popup, highlights when you’re on a supported dndbeyond.com page, and never transmits your data anywhere, everything stays local. Works on Firefox (desktop/mobile) and Chromium browsers and includes instructions plus MIT license in the package.
