Version 75.0beta, first offered to Beta channel users on March 10, 2020
Firefox 75 will, in the background, locally cache all trusted Web PKI Certificate Authority certificates known to Mozilla. This will improve HTTPS compatibility with misconfigured web servers.
Type less, find more with Firefox’s revamped address bar. Now, just select the address bar, and a box will expand with links to your top sites. A redesigned interface provides a focused, clean search experience that’s optimized for smaller screens. Solutions to common browser issues now provided right in the search suggestions box.
Experimental support for using client certificates from the OS certificate store can be enabled on macOS by setting the preference security.osclientcerts.autoload to true (this feature has been available on Windows since Firefox 72).
