v0.1.0-alpha

First public alpha. BurnerCookie is a Firefox MV3 extension that burns consent cookies and per-domain storage on listed publisher sites when their tabs close. It targets IAB TCF publisher tracking specifically and leaves the rest of your browsing alone.

This is the per-site container wiping build that was announced. It loads unsigned through Firefox.

What it does

• Opens listed publisher domains in throwaway Firefox containers.
• Destroys the whole container on tab close, which atomically wipes cookies, localStorage, IndexedDB, and cache for that session.
• Ships a bundled list of ~141 known IAB TCF publishers across Schibsted, Axel Springer, Condé Nast, Hearst, DMG Media, Reach, and Bonnier.
• Supports a personal list and auto-refreshing subscription lists.

What it does not do yet

It does not chase third-party vendor cookies across other domains. That feature was built, failed its parent-domain QA on dailymail.com, and was pulled rather than shipped half working. It returns in v0.2, fixed and re-tested. See ROADMAP.md.

It is also not a content blocker, not a fingerprinting defense, and not a defense against authenticated identity resolution or server-side consent records. It is complementary to uBlock Origin, Firefox Total Cookie Protection, a VPN, and email aliases, not a replacement for any of them.

Install

Loads unsigned through Firefox. Open about:debugging, click This Firefox, Load Temporary Add-on, pick manifest.json. Firefox 115 or later. Not on AMO and not signed for persistent install, that is the v1.0 milestone.

Testing and privacy

Tested end to end on aftonbladet.se and svd.se against Firefox 115+. No telemetry, no analytics, no external calls except the subscription lists you add yourself.
