Whitelist-Blacklist-Blocker od Prog.JMC

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.
