Salesforce seemingly randomly displays the following error message on Firefox Nightly (started in FF 95, continuing in FF 96). **We can't display this page because your browser blocks cross-domain cookies. Try again with a different supported browser.** When the error message starts happening, I am able to get it to stop by turning off Enhanced Tracking Protection via the shield icon in the Firefox address bar. Explanation by Dan Veditz: "Standard" is fine, doesn't need to be "off". The problem is dynamic First-Party Isolation (dFPI) which is newly part of "Strict" in nightly. Screenshots are available here: https://bugzilla.mozilla.org/show_bug.cgi?id=1712018#c17
