Mozilla has launched Firefox 160, rolling out an experimental multitasking feature called Mini Windows. The update introduces always on top floating page snippets, native speed sliders for Picture in Picture video, and broader audio codec support for MKV files. The updated browser is now available for download across desktop operating systems.
Mini Windows allows users to detach individual tabs or page sections into small floating windows that stay on top of other desktop applications. Right clicking a tab opens the Move to Mini Window command. For partial page content, users open the context menu on any web page element and select Move Section to Mini Window to highlight and separate that specific zone. The Picture in Picture tool adds a button and speed slider directly to the video overlay. Viewers can change playback rates inside the floating player without switching back to the source tab.
Firefox 160 adds native playback for MKV media files containing FLAC, MP3, and PCM audio tracks. On macOS, the browser shifts WebGL rendering to the Apple Metal graphics interface to increase performance on complex visual sites. The release resolves visual glitches in the address bar and fixes issues with background links launching from external software. Exporting web pages to PDF documents now preserves MathML mathematical data for screen readers, assisting visually impaired users with educational content.
