While presets are convenient, you may need a specific refresh time that isn't listed. The custom time interval feature allows you to define your own refresh rate in seconds or minutes.
The extension requires a minimum interval 1 second to prevent abuse or browser crashes. If you enter an invalid number or a value below the limit, the input field will show an error.
Custom intervals are useful for syncing with specific events, such as a website that updates its data every 45 seconds, or for setting a very specific long interval, like 22 minutes.
