Firefox 126 release information

Firefox Desktop

Guidance notification on how to set Firefox as a default browser (Windows only)
Description:	Users are no longer able to set Firefox as the default browser with one click – Windows is forcing users to navigate to the Windows Setting. In response, we are planning to land a "Guidance notification" in Fx126 to help educate users in the process and on the notifications there is a "show me how" that will lead to a SUMO page to explain.
