New
- Choose which feed features appear. Under Settings → Feeds, you can now hide Live Bookmarks from the Bookmarks menu and turn off previews of directly opened feed URLs. These settings are independent of feed discovery. Turning previews off leaves the original feed document open.
- Open feed articles in a new tab or window. The open article setting now includes Open the original article in a new tab and Open the original article in a new window, alongside the existing reader and open article options.
- Close ordinary tabs with a double-click. A new option under Settings → Appearance → Tab bar enables double-click closing. Tree tabs continue to use their own double-click setting.
Changed
- Switched to Noto Color Emoji with Unicode 18.0 support on platforms without native emoji support or where individual emoji characters are missing.
- Compact density now reduces spacing in Waterfox’s custom menus.
- The Web Share API is enabled only on Windows, where a native sharing picker is available. Websites on macOS and Linux can use their fallback sharing controls instead of offering a share action that fails.
Fixed
- Security fixes described in Mozilla Foundation Security Advisory 2026-108.
