I connected the extension to the dummy backend, so it now blocks sites according to the database. It also saves a small local cache (resets on restarts) so it isn’t constantly pinging the DB for sites it’s already accessed. There was a pretty confusing hiccup where just typing something in the URL bar would close the tab before you loaded anything, but I eventually realised it was actually the search completion API (since I had blocked Google for testing, it was auto-blocking it).

I also made a simple blockpage so it doesn’t just close the page with no explanation.

AI disclosure: AI was used to help me 1. realize I needed to put the blockpage files as an entrypoint and not in the public/ folder and 2. to fix issues with CSS because it’s an absolute nightmare
