Download CookieVault

TL;DR: CookieVault Editor and Guardian are Manifest V3 extensions you install from the Chrome Web Store (Chrome, Edge, Brave, Opera, Vivaldi, Arc), Firefox Add-ons, or as a signed CRX from GitHub. Free, no account required, auto-updating from the official stores.

CookieVault is distributed as two independent Manifest V3 browser extensions — Editor (cookie management) and Guardian (auto-delete on tab close) — available through the official extension store for each browser, with full source code on GitHub for users who prefer to self-build. Installation is free, requires no account, and the store builds auto-update.

Which extension do you need

In short: Editor is the EditThisCookie replacement (view / edit / export cookies). Guardian is the Cookie AutoDelete replacement (auto-clean on tab close). They are independent — install one, the other, or both.

Install by browser

In short: Chromium browsers (Chrome, Edge, Brave, Opera, Vivaldi, Arc) use the Chrome Web Store build. Firefox uses a separate Firefox Add-ons build. All other installs go through the signed CRX on GitHub.

Store listing URLs are finalized at public launch. Until then, the GitHub release page hosts signed CRX packages for every supported browser.

The five-step happy path for any Chromium browser:

  1. Open the Chrome Web Store listing for CookieVault Editor (or Guardian)
  2. Click “Add to Chrome” (the button text varies by browser: “Add to Brave,” “Install,” etc.)
  3. Review the requested permissions and confirm
  4. Pin the toolbar icon for one-click access (puzzle-piece menu → pin)
  5. Click the icon to open the extension and start managing cookies

The store install auto-updates whenever a new release ships, so you always have the latest security fixes.

Install via signed CRX (advanced)

For users who prefer not to use the Chrome Web Store, or for browsers that need side-load:

  1. Open the GitHub release page for the version you want
  2. Download the signed .crx file and the matching SHA256SUMS file
  3. Verify the checksum: sha256sum cookievault-editor.crx and compare to the published value
  4. Open chrome://extensions and enable Developer Mode (top-right toggle)
  5. Drag the .crx onto the extensions page and confirm
  6. Note: side-loaded installs do not auto-update — re-download for new releases

Build from source

CookieVault is MIT-licensed and reproducible-built. To build it yourself:

  1. Clone the repository from GitHub
  2. Run npm install
  3. Run npm run build — output lands in dist/
  4. Open chrome://extensions, enable Developer Mode, click “Load unpacked,” and select the dist/ folder

Reproducible builds mean the binary you build matches the binary in the store for the same tagged commit — verify by comparing SHA-256 checksums.
