BP Cookies Manager gives developers, testers, and privacy-focused users direct control over current website cookies.

Before you start using BP Cookies Manager

BP Cookies Manager works on the current browser tab. Open a normal website first, then open the extension from the toolbar. Internal browser pages such as extension settings do not expose normal website cookies.

Cookies can contain active login sessions, authentication tokens, preferences, cart data, tracking IDs, and A/B test values. Treat exported cookies like sensitive data.

Best forDevelopers, QA testers, account/session debugging, cookie audits, and manual privacy workflows.
Current tab focusThe popup shows cookies available to the active website, including parent-domain cookies when the browser exposes them.
Local processingCookie data is processed in your browser by the extension.
Safety ruleNever share exported login cookies with anyone you do not trust.

Home shows the current website, cookie count, search, sort, Add Cookie, Delete All Cookies, and the cookie list.

1. View and search current website cookies

The Home screen is the main cookie viewer. It lists cookies for the current website and lets you filter them by name, value, domain, or path.

  1. Open the website you want to inspect.
  2. Open BP Cookies Manager from the toolbar.
  3. Check the site card and cookie count.
  4. Search by cookie name, value, domain, or path.
  5. Sort by cookie name, newest first, or expiration date.
  6. Use the cookie actions to edit, delete, or block specific cookies.

2. Add or edit a cookie

Use Add Cookie to create a new cookie, or use the edit action beside an existing cookie. The editor supports the fields developers need for real browser testing.

  1. Set the cookie name and value.
  2. Choose the domain and path. The domain must match the current website.
  3. Set expiration, or mark it as a session cookie.
  4. Choose SameSite: Unspecified, Lax, Strict, or None.
  5. Enable Secure for HTTPS-only cookies.
  6. Enable HTTP only when page scripts should not read the cookie.
  7. Save the cookie and refresh the website if the app needs to re-read it.

SameSite=None requires Secure in modern browsers, and Secure cookies require HTTPS.

The cookie editor exposes name, value, domain, path, expiration, SameSite, session, Secure, and HTTP-only fields.

3. Delete one cookie or all current website cookies

Delete a single cookie when you want a targeted reset, or use Delete All Cookies when you want to clear every cookie listed for the current website. This is useful for session debugging, logout testing, cart testing, consent banner testing, and account-flow troubleshooting.

Delete one cookie Use the delete action beside a specific cookie when only one value needs to be removed.
Delete all listed cookies Use the Delete All Cookies action when you want a clean current-site cookie state.
Why cookies return Some websites recreate required cookies after reload. Use blocking for names that should keep disappearing.

Blocked cookie names are removed whenever the current site creates them again.

4. Block recurring cookie names

The Blocked Cookies screen is for names that keep coming back. Add a cookie name, such as _ga, and BP Cookies Manager removes matching cookies when the site recreates them.

  1. Open Blocked Cookies.
  2. Enter the exact cookie name.
  3. Click Block Cookie Name.
  4. Reload or browse the site normally.
  5. Remove the name from the blocklist when you want the site to keep that cookie again.

The browser reports cookies after they are created, so a blocked cookie can exist briefly before the extension removes it.

5. Import and export cookies

The Import & Export screen moves cookie data between tools and browsers. BP Cookies Manager supports three practical formats.

JSON Backup Best for complete cookie data and repeatable testing.
Netscape File Useful for many browser, command-line, and automation workflows.
Cookie Header Use the familiar name=value; name2=value2 request-header format.

Only import cookies from sources you trust. Imported authentication cookies can grant access to accounts.

6. Detect new cookies after a page load

When a finished page load creates new cookies, BP Cookies Manager can show an in-page notification. Click the notification to open the cookie manager with those new cookies highlighted.

This is useful for seeing what changes after login, consent banner acceptance, checkout steps, form submissions, analytics scripts, or account redirects.
