threshold by Samuele Littek-Rolt

A simple website blocker I made in an afternoon; originally meant as a ScreenZen-like extention for Firefox. It makes you take a mindful pause before distracting sites, with a timed session and automatic re-block.

About this extension
Threshold is a Firefox extension that intercepts distracting sites with a countdown pause before granting access. Sessions auto-expire and re-block the site. Configure pause length, session duration, and daily opening limits from the popup.
