For most Windows users, the existing desktop shortcut for launching Firefox
has been replaced with the desktop launcher, a small program that will launch
Firefox if it is installed, but if it is not installed will prompt the user
to install Firefox. This will provide an easy installation point for Firefox
users who acquire a new Windows device, where Firefox will not be installed
by default, but the desktop launcher program may have synced via OneDrive or
other cloud storage product. Learn more.

been updated for consistency.
When no extensions are installed, clicking the Extensions button now

links to the Firefox Add-ons store.

browsers that translate using cloud services.
