JWT EZ Copier by Elias Junior

Bearer Trace helps developers testing APIs see the Bearer token of the open tab and copy it in one click.

Instead of opening the browser tools, going to Network, finding the request, and copying the Authorization header, the extension shows the current token from the Firefox toolbar.

How it works
• Watches the tab's requests and shows the latest Bearer token.
• Adds a new history row only when the token changes.
• Copy with the button or with Alt+Shift+B.
• The token stays hidden until you choose Show.

Privacy
The token, URL, and history stay in Firefox local storage. The extension has no server, creates no account, and does not send this data anywhere. Closing the tab, or using Clear, removes that tab's record.

Who it is for
Development and debugging of your own applications. A token is an access credential: use it only with APIs you are already allowed to call.
