Trouble Logging in to lemmy.ml with Firefox (lemmy.ml)

Fellow reddit refugee here. I'm having trouble logging in using LibreWolf (basically firefox) with multi account containers turned on. I can log in fine with Chrome or in a LibreWolf Private Window, and most other sites work fine, so apparently I've got something configured weird or lemmy.ml is doing some weird cross-site authentication or setting a cookie from another site.

I have lemmy.ml set to always use a Lemmy container, Google set to always use a Google container, Hachyderm.io using a Mastodon container, etc., and those all work fine, but Lemmy just spins when I click the button to log in.

Anyone know what else I should whitelist to log in normally?

I'd need to see the browser console logs to figure out what's going on. But it sounds like a plugin you're using is blocking the cookie from being set.

Thanks for the quick response! It's almost certainly a tracking protection or a 3rd party cookie. Are you setting any 3rd party cookies or is some other authentication happening? I'll see if I can grab the console logs for you, too, if I don't figure it out soon.

Looks like this might be the issue? I get this warning in the console when logging in with a Private window, and I think LibreWolf is blocking it (firefox.exe is blocked at work so I run librewolf portable there)

Cookie “jwt” does not have a proper “SameSite” attribute value. Soon, cookies without the “SameSite” attribute or with an invalid value will be treated as “Lax”. This means that the cookie will no longer be sent in third-party contexts. If your application depends on this cookie being available in such contexts, please add the “SameSite=None“ attribute to it. To know more about the “SameSite“ attribute, read https://developer.mozilla.org/docs/Web/HTTP/Headers/Set-Cookie/SameSite

Hrm.. didn't know about that one. I'll open up an issue in lemmy-ui for it.
