A common worry with Auto Refresh is losing work mid-task: you are filling in a form or reading a long article, the timer hits zero, and the page reloads from under you. The fix is built in — Auto Refresh can pause itself the moment you interact with the page, so the reload only happens while you are away.
The setting that controls this is "Stop refreshing if click anywhere on the page" in the Advance Options panel. When you are done and want the timer to resume, restart it with the default shortcut Ctrl + D (customisable from the Refresh List).

Refresh only on current tab
Stop after 3 number of auto refresh
Show visual timer on the webpage
Stop refreshing if click anywhere on the page
Hard Refresh
From this point on, any click, keystroke or scroll on the page pauses the timer. Your form data, scroll position and selection stay intact for as long as you are interacting with the page.
