Excellent add-on that gives you fine-tuned control over what you block and what you allow. I use this add-on to block sites that I feel addicted to (mostly social media) and it has vastly improved my life.

My suggestions to make this add-on even better:

- A checkbox to disable the footer ("enter password" or "allow site") so I can't just easily unblock the site
- Make the "Save" button more pronounced. It's the most important button but very easy to miss!
- Rule sets/categories such that I can have separate sets of rules, e.g. "social media blocking", "news site blocking", etc, and activate whichever ones I need to.
