As you may already know, your login status is stored in a cookie. By default, Firefox allows the NYT site(s) to set persistent cookies that are good until they expire. If you use private windows, or block cookies, or clear cookies when Firefox closes, that would prevent the site from recognizing that you already logged in the next time you start up. But if you already have the site open and logged in in one tab, and you create a new tab (Ctrl+T) and click a bookmark to the site in the new tab, then the cookie should be shared across between those tabs. Is that working at least, or is that not working either? There is another NYT thread where the top part of the page shows the user is logged in, but the lower part of the page behaves like he is not. Which is very strange and unsolved at this point. Here's a link to that thread to compare problems and suggestions: https://support.mozilla.org/questions/1390422
