What Tab Resize does
Tab Resize takes your current tab, along with tabs to its right (or any tabs you've highlighted), and arranges them into separate browser windows following a layout you pick, such as a 1x2 or 2x2 split. It supports multiple monitors, letting you drag windows between screens, and lets you add or remove layouts to match your setup.
Why separate windows instead of panes
Unlike extensions that split a single tab into multiple panes, Tab Resize moves tabs into their own windows. The developer notes this avoids the security restrictions some multi-pane extensions run into on sites like Gmail or banking pages, and it keeps your other extensions working normally in each window.
Is Tab Resize safe?
Tab Resize is a window-management tool focused on rearranging existing browser windows and tabs into layouts. It's free to use, with development history and issue tracking maintained publicly by the developer on GitHub.
