Mozilla has re-enabled TLS 1.0 and 1.1 in the Firefox Stable and Beta browser; it is unclear when Mozilla did that but an update on the Firefox release notes page highlights why the protocols have been enabled again. Mozilla notes:
We reverted the change for an undetermined amount of time to better enable access to critical government sites sharing COVID19 information.
