In the Auto Refresh Plus extension for Chrome, the “Random Time” interval option allows you to specify a range of time within which the extension will randomly select a time interval for refreshing the page. This can be useful if you want to refresh the page at random intervals rather than at a fixed interval.

To set a random time interval, you will need to follow these steps:

1. Click the Auto Refresh Plus icon in the Chrome toolbar.
2. Click the “Options” button.
3. In the options page, locate the “Enable Random Interval” toggle and turn it on.
4. When you next open the extension’s toolbar popup, you will see the “Random Time” option available in the “Time Interval” section.
5. To specify the range of time within which the extension will randomly select a refresh interval, enter a value in the “From” field and a value in the “To” field. For example, if you want the interval to be randomly selected from a range of 10 to 20 seconds, you would enter “10” in the “From” field and “20” in the “To” field.
