Bypass the NZHerald paywall. I made this mostly for myself.
What is NZHerald Bypass?
Note: I have stopped supporting this extension. I recommend others have a look at this extension instead: https://github.com/iamadamdev/bypass-paywalls-firefox.
NZHerald Bypass is relatively safe to use as it requires very minimum permissions.
NZHerald Bypass has earned a fairly good reputation and likely can be trusted.
