Delete current site cookies (including subdomains)

[i486]

It blows my mind that there is no one-click addon for clearing site data from current site including the subdomains.

For example

1. Open hulu.com
2. Open help.hulu.com

Open the hulu.com tab and click "Delete current Site Cookies" on CCM. It will only delete cookies from hulu.com, but not help.hulu.com.

I guess it's probably intentional or by design.

But look, Firefox's own method clears both domain and subdomain cookies.

1. Open hulu.com
2. Open help.hulu.com
3. Open hulu.com tab
4. Open Page Info (Ctrl+I) and Security > Clear Cookies and Site Data > Remove
5. All cookies from hulu.com and help.hulu.com are cleared.

If it's doable, it would be great to have this feature in Cookie Quick Manager.

Delete current Site Cookies
Delete current Site Cookies (incl subdomains)
Delete current Context Cookies
Delete current Site LocalStorage

or option in addon settings section to make "Delete current Site Cookies" delete subdomains.

Honestly, I'd actually prefer entirely different one click addon that does this.

We already have this one. Sadly, it also doesn't delete subdomains and author seems to be have abandoned the project.

Does anyone know any place where i can request new addon to be developed?

EDIT: Cookie AutoDelete does clear subdomain cookies. Although not a one-click solution, it does what i've requested above.
EDIT: Found one-click alternative that actually clears subdomain cookie. Sadly it doesn't clear LocalStorage.
