Partitioned Cookies/Values Not Shown

[VoidedStars]

When trying to view cookie values with Cookie-Editor v1.13.0 in Firefox 141.0.3 I noticed that one part of the cookie I was examining was missing. On using the developer tools to examine storage, I found that it had a partition value listed (more information: https://developer.mozilla.org/en-US/docs/Web/Privacy/Guides/Storage_Access_Policy/Errors/CookiePartitionedForeign ). I believe that this partitioning feature is preventing Cookie-Editor from properly seeing all of the cookies/values for a site.

I attempted to disable cookie partitioning to verify if that fixed it, but I was either doing something wrong, or Firefox simply ignores the settings (which wouldn't be a first).

Steps to reproduce:

1. In Firefox, go to https://www.youtube.com/, and open the web developer console.
2. Navigate to "storage", expand "cookies", click on https://www.youtube.com/, then enter "rollout" into the filter.
3. You will see two rollout values, one with a partition key of https://youtube.com/. Take note of both values here.
4. Open Cookie-Editor while still on YouTube, and search for rollout. There should be only 1 rollout value, which matches the non-partitioned cookie.
