I have the same issue, but I don't see the same thing.
I have bookmarks set up with URLs like your first set:
company1.sigin.aws.amazon.com
...
But as soon as I click one, it gets redirected to:
signin.aws.amazon.com/oauth?<War and Peace>
Which is interpreted as the same URL for all accounts.
One solution would be to have FF containers tie into the bookmark editing code so we can set the container by bookmark. That is, when I click a bookmark with a container set, that container should be used to open the site regardless of the URL.
