Whitelist Feature?

 Hello everyone!

I got a new feature request here recently from a user who goes by "pakxo" - they're curious if a whitelists feature could get added to save on processing for known good sites.

Currently, there's a basic, non-configurable whitelist. It helps handle the edge case where sometimes captcha images would get blocked, which is quite frustrating.

If anybody else would like to see this added, let me know through the feedback link in the addon! And again - thanks pakxo for the idea!
