nogo: site blocker/redirector wót lennacodes

nogo is a simple website blocker and redirector for Firefox.

Block sites — Add any domain to your block list and it will be completely
blocked, including all subdomains.

Redirect sites — Set up rules to automatically redirect one site to another
(e.g., reddit.com to wikipedia.org). A brief "redirecting to a safe site..."
screen is shown before navigating.

60-second removal cooldown — When removing a site from your block list, a
60-second countdown timer makes you pause and reconsider before confirming.
This helps you stay intentional about your browsing habits.

Privacy first — All data is stored locally on your device. nogo does not
collect, transmit, or share any user data.
