Pause page is a free Chrome add-on developed by oliverjash that allows users to instantly pause the page when DevTools is open using a keyboard shortcut. This feature makes it convenient for users to inspect an element at a specific point in time.

When using DevTools to inspect elements like popovers or dropdowns, their visibility is often controlled using JavaScript events like `mousemove` or `mouseleave`. As a result, when trying to inspect these elements, they may disappear from the page due to cursor movement or keyboard focus changes. By pausing the page once the element is visible, it remains on the page even if the cursor moves or keyboard focus changes, allowing users to inspect the element and its styles effectively.

With Pause page, users can easily pause the page with a keyboard shortcut, saving time and eliminating the frustration of elements disappearing during inspection. This Chrome add-on is a valuable tool for web developers and designers who rely on DevTools for efficient debugging and troubleshooting.
