This WILL only occurr if you're blocking first-party cookies either via uMatrix or via Firefox's Content Blocking options. Since you're not blocking cookies via uMatrix, the latter is causing this. Anyways, this is not a uMatrix issue.

He may have changed the rules without trying to force reload the page in order to bypass the browser cache.

Disable blocking all cookies or set it to third-party and you will be able to login.

About "the page is still broken after I created all necessary rules"

Disable blocking all cookies or set it to third-party and you will be able to login.

I did have "block all cookies" in FF itself enabled. I wasn't aware this would still "matter" assuming when µM takes over control it does so exclusively. My bad, sorry. Does this apply to javascript, too?

It doesn't take control over the browser, Extensions have restrictions too.
