Firefox adds Mini Window for multitasking in beta, stable release set for November
Mozilla has rolled out a new feature called Mini Window in Firefox Nightly, its beta testing channel. The tool lets users pop out tabs or sections of tabs into a floating window that hovers over other Firefox windows, aimed at improving multitasking on devices with limited screen space. The feature is scheduled to reach the stable Firefox release on November 10.

What Mini Window does
Firefox’s Mini Window allows users to detach a tab or a specific section of a tab into a separate, floating window. This window hovers above other Firefox windows, making it easier to reference content without switching between tabs or windows. Initially, the Mini Window appears as a minimalist web app, devoid of browser elements like the address bar or scroll bar. However, hovering the cursor inside the window reveals controls such as the address bar, navigation buttons, and a close button.
The feature is designed to address multitasking challenges, particularly on smaller screens like laptops. It also bypasses limitations in macOS’s Stage Manager, which restricts users to a single active window at a time.
How to test Mini Window now
Mini Window is currently exclusive to Firefox Nightly, Mozilla’s beta testing channel. Users can install Firefox Nightly alongside the stable Firefox release to try the feature. To pop out a tab, right-click on it and select Move Tab > Move to Mini Window. To move a specific section of a tab, highlight the content, right-click, and choose Move Section to Mini Window.
How it compares to Chrome’s alternatives
Chrome offers two features with superficial similarities to Mini Window: Picture-in-Picture mode and Mini Player. Both are limited to video and media playback, however, and lack the ability to pop out entire web pages or sections of tabs. Firefox’s Mini Window extends this functionality to any web content, not just media.
Mozilla’s recent Firefox updates
This launch follows Mozilla’s broader efforts to enhance Firefox’s utility and enterprise readiness. In June, the company released Firefox Enterprise, a version tailored for European companies and public bodies requiring strict security, compliance, and governance controls. Earlier this year, Mozilla also redesigned Firefox with a compact mode, catering to users who prefer a more streamlined browsing experience.
These updates reflect Mozilla’s focus on adaptability, whether for individual users seeking productivity tools or organizations prioritizing digital sovereignty and security.
What this means
Lazyfounder analysis — our interpretation, not reported fact.
For founders and operators building web applications or tools that rely on browser-based workflows, Firefox’s Mini Window introduces a new way to think about user multitasking. Unlike Chrome’s media-focused features, Mini Window extends floating window functionality to any web content, which could inspire innovative UX designs for productivity tools, dashboards, or collaborative platforms. Teams targeting users with limited screen space—such as remote workers or laptop-heavy audiences—may find this feature particularly relevant for improving workflow efficiency.
