Good afternoon,

We're currently trying to set up a Hardening Guide for Firefox ESR but are struggling with a few policies and setting wildcards.

For example, we're trying to set an origin in Cookies > Block Settings to something like "*", and we get the error "Ignoring parameter "*" - not a valid origin."

In Chrome / Edge you can set a wildcard like this: [*.]google.com for example - we receive the same error message for this.

Can you do such a thing for Firefox ESR without having to list every site you want to block?

ESR Version: 115.6.0esr (64-bit)

Kind Regards, Ethan Jerrum

Isisombululo esikhethiwe

Are you using Firefox policies?

With the cookie policy:

https://mozilla.github.io/policy-templates/#cookies

You set it to reject all cookies ("reject") and then specify the sites to allow.

I've attached a screenshot of where this is in the Firefox UI.

If you say https://google.com and http://google.com permissions, it will block subdomains as well.

Hi Mike,

Yes this is good but we want to Block all sites from setting cookies apart from those in the Allowed Sites list, does this make sense?

Kind Regards, Ethan
