[feature request] A NSFW filter

[codemonstur]

I'd like an option to automatically delete all entries for NSFW websites.

That seems to be a difficult request. How would the addon know which sites are NSFW?

You can:

• match hostnames against a blacklist
• match against known keywords
• allow users to add sites to the hostname blacklist

The list doesn't have to be extensive. Most are pretty obvious.

Not difficult to implement, there are public and regularly updated NSFW domain filter lists.

This one is used by many DNS-based blockers: https://oisd.nl/
