Firefox 111.0 new features and improvements
Native notifications support on Windows
The big new feature in Firefox 111 is native notifications support on Windows. More precisely, support is available on Windows 10 and newer versions of Windows, including Windows 11.
Notifications were displayed as small overlays in the Firefox web browser up until now. With Firefox 111 comes support for the native notifications system on Windows, which means that notifications are displayed using it.
This offers several advantages, including that recent notifications may be displayed again. Firefox notifications vanished after a few seconds automatically, which sometimes meant that users had no time to read it before the information was removed.
You can check out my detailed Firefox notifications guide for Windows, which includes information on disabling the feature and returning to the previous default.
