Other additions include QR code generation from the tab context menu, PDF drag-to-merge and image-as-page insertion, more address bar quick actions (color picker, Firefox Labs), rounded bottom corners enabled by default on GTK/Linux desktops, HDR video playback on Windows, Apple Globe+F full-screen support on macOS, and a URL bar on the New Tab page. This is the last monthly release before Mozilla switches to a two-week release cadence. ## Full article daily.dev links to this article rather than hosting it.
