Hi

Hi everyone,

I’m regularly hitting Anubis [https://github.com/TecharoHQ/anubis](https://github.com/TecharoHQ/anubis) proof-of-work challenges and instead of the challenge completing, I always get the “Oh noes! Your browser is configured to disable cookies” error page (currently seen with Anubis v1.25.0).

Setup:

- Mullvad Browser (latest), macOS 27, without VPN
- Default settings — I’m aware private mode and first-party isolation are on by design
- Happens across many different open-source sites running Anubis, so it’s clearly not site-specific

From what I understand, Mullvad Browser breaks Anubis’ flow because it can’t reliably set the challenge/verification cookies.  
Questions:

1. Do other Mullvad Browser users see this as well?
2. Has anyone found a workaround that doesn’t defeat the purpose of the browser?
