Quad Tabs - Split your Browser

Try using this split browser extension. Here are some of the many reasons/benefits of using this software.

Content creators constantly cross-reference source material: designers view brand guidelines while tweaking Figma, writers quote studies while drafting articles, and marketers A/B-test landing pages against competitors. A split extension locks both sites in the same window, eliminating ALT-TAB whiplash and ensuring elements line up to the exact pixel when you scroll in tandem.

2 | True Multitasking on Ultrawide Monitors Modern 34-inch and 49-inch displays offer abundant real estate, yet operating-system tiling often wastes it with window chrome and menu bars. Browser-level splitting keeps toolbars to a minimum, so every extra inch translates into more code, more spreadsheet columns, or a wider kanban board—perfect for power users who run dashboard-heavy workflows.

3 | Lightning-Fast Research Loops Students, analysts, and journalists juggle articles, PDFs, and citation tools. A split view pins your note-taking app next to a live encyclopedia, letting you drag facts or quotes directly across panes. The instant feedback loop encourages deeper exploration and sparks connections that bouncing between tabs might obscure.

4 | Streamlined Remote Collaboration During video calls, presenters often show demos in one tab while taking questions in another. A split extension embeds the chat or meeting controls beside the live site, so you can scroll, click, and respond without flashing conference-room participants with your cluttered desktop. Fewer pauses equal smoother, more professional sessions.

5 | Synchronized Testing for Responsive Design Developers testing mobile versus desktop breakpoints normally resize separate windows or rely on DevTools emulators. Splitting the window into 375-px and 1440-px panes allows immediate side-by-side comparison of navigation behavior, font scaling, and media queries, catching inconsistencies before they reach QA—and without leaving your primary editing environment.
