Delay certain urls from displaying
Identify and remove the habits that have you unintentionally opening websites.
Create a list of URL's and they will have a delay before the websites displayed. The delay enables you to recognise you've opened a certain URL and gives you time to to acknowledge a typically unconscious decision.
Each time you both navigate to a blacklisted URL and wait for the delay to resolve it will save an event. These can be viewed in a chart which will compare how many times you navigated vs how many times you let the delay load. This way you can visualise how many times you halted that habit and delay rescued some time!
