Features & Capabilities

Browser SplitView Master is a premium, high-performance workspace utility that allows you to divide a single browser tab into up to 16 independent, resizable grid panels. Perfect for developers, QA testers, researchers, and multi-taskers who need to view and interact with multiple sites side-by-side without managing cluttered browser windows.

Key Features:

Multi-Panel Grid Splitting: Vertically or horizontally split any panel with a single click. Resize boundaries dynamically using smooth drag handles without reloading iframe contents.
Intelligent Scroll Synchronization: Toggle simultaneous scroll tracking to browse multiple pages, documents, translation layouts, or site versions in perfect real-time coordinate sync.
Responsive Viewport Emulation (New): Toggle individual panels between Desktop (100%), Mobile (375px), and Tablet (768px) preview frames to quickly test media queries and responsive styling.
Viewport Screenshot Capture (New): Take and download a cropped, high-DPI PNG screenshot of a single panel's viewport with one click. Safely captures content from cross-origin sites by bypassing CORS restrictions.
Local File & Path Support (New): Open local filesystem templates and Windows drive paths directly. Paths are automatically normalized to valid file:/// URLs.
Layout Bookmarks & Sessions: Save your custom split grid configurations and easily load them later in one click. Layouts persist automatically across browser sessions and tab reloads.
Quick Templates: Launch popular grid configurations instantly (1x1, 1x2, 2x1, 2x2, 3x3, and 1x3) from the sidebar.
Adaptive Sandbox Framing: Built-in local sandbox controls dynamically strip blocking headers (X-Frame-Options and Content-Security-Policy), allowing you to frame and compare websites seamlessly.
Privacy-Focused: Operates entirely locally. No external databases, no analytics trackers, and no remote data transfers. All settings are saved directly in your browser's secure local storage.

Perfect For:

Testing responsive web layouts side-by-side on mobile, tablet, and desktop viewports.
Comparing source pages, staging vs. production, or developmental updates.
Taking clean layout screenshots for design review, bug reporting, or documentation.
Cross-referencing document translations or side-by-side code previews.
Monitoring live analytics, server metrics, or social feeds concurrently.
Comparing prices, specs, and reviews while online shopping.

Is Browser SplitView Master Safe?

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Browser SplitView Master requires a few sensitive permissions. Exercise caution before installing.

Risk impact analysis details

Critical Allows access to all websites, posing a significant security risk as it can monitor and modify data from any visited site.

Risk likelihood

Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

Browser SplitView Master is recently added, and hasn't been around long enough for us to gather enough data to accurately assess its risk level.
