hoverinteraction

Hover interaction in Chrome refers to the browser's use of mouse hover events as a signal to prefetch or prepare web pages before a user clicks. This technique aims to make browsing feel faster without the heavy memory costs of full prerendering. Recent experiments in Chrome Canary include hover-prefetch and a render boost that prioritizes active page loads. These changes re-open trade-offs around privacy, resource use, and potential side effects for websites and users. The tag covers discussions on how hover-based optimizations work, their impact on performance, and the underlying Chromium code changes.
