Test if your website blocking tools are working effectively
A blocker is working when the distracting site fails in the same browser, profile, and time window where you normally get distracted. Test the exact site, subdomain, and app path you use, not just the homepage.
Browser extensions are easiest to install, hosts-file and DNS rules are harder to bypass, and dedicated blocking apps are best when you need scheduled locks across multiple browsers or devices.
Re-test after browser updates, extension changes, new devices, or whenever you notice yourself reaching a distracting site during a focus session.
If a site still opens, add both the root domain and common subdomains, then test from the same profile you use for work or study.
For serious focus blocks, test the blocker before the timer starts. Fixing rules during a session usually becomes another distraction.
