Is HackBar safe?

Clean risk

HackBar stores active-tab POST form data and request headers so its devtools panel can replay them.

When a main-frame page submits a POST, HackBar stores the active tab's URL, form fields, and selected request headers, including cookies, referrer, and user-agent, in its background script. Its devtools panel can read that stored data back for replay inside the extension. No external recipient is identified in the reviewed claim.
