Limits on the Go
When enabled, Limits on the Go allows you to enter session based usage limit for the selected Blocked Websites. It's particularly useful if you don't want to initially have a fixed limit for a website, but still want some kind of control over your usage.
Keep in mind that "Limits on the Go" should be activated via a Schedule or manually by clicking on the "Activate" button. When it is activated, given blocked sites will ask you to pick a session-based usage limit when you enter into the website at the beginning.
Depending on the action you select, Limits on the Go blocks your further usage within the same session or sends you a notification indicating the given time limit is up.
