Whitelist-Blacklist-Blocker Firefox

Whitelist-Blacklist-Blocker

A site blocker that closes a tab if a blocked site is loaded. Sites can be whitelisted or blacklisted with regular expression rules and if a site is matched it is 'blocked'.

Features & Capabilities

This was mostly made for my own use as I couldn't find an add-on that met my needs. ie.) I want to visit reddit.com/r/cooking to look for recipes but I don't want to be distracted by reddit.com/r/all.

Blacklist : .reddit.com/r/. Whitelist: .reddit.com/r/cooking.

( ".*" is the wild card of any length and is a good catch all to wrap around your entries)

Updates to the whitelist and blacklist are done via the toolbar-icon. New entries are separated by a new line.

I'm open to suggestions and improvements if anyone else finds this tool useful.

TODO:

  • Improve user experience and whitelist / blacklist editing experience.
  • Fix a known issue where rendering is sometimes delayed and interaction with the popup is necessary for the editor to load.
