I’m migrating from Brave. I have a whitelist of (sub)domains that I allow to save cookies, a blacklist that’s never allowed, and the rest get deleted when I close my browser.
I ported this list to LibreWolf but I cannot find an option to view exactly which domains are setting cookies. For example, on YouTube, accounts.youtube.com is enabled to keep me logged in. But when I click the settings icon on the search bar, it only gives me the option to delete cookies for youtube.com and doesn’t list which domains are setting cookies. This is fine for youtube because I already know but not alright for new websites that I might use.
The rules doesn’t accept regex either. So if I want to block accounts.google.com, I cannot block *.google.com. I have to block the domain and all the subdomains individually. Which is even harder because of the first issue.
Firefox’s cookie management is absolutely terrible and anachronistic, forget about automated granular control. It also has serious bugs like this one, it’s better to use containers for any site where you want a whitelist.
There are some addons to help you manage it, but I think they are all flawed or broken.
