ByPass Paywall add-on in firefox is not working with paywalled sites. Alternatives?

As the title says. I am using the ByPass Paywall add-on and it used to work, but since some time it just doesn't. I've made sure the site I am trying to visit is listed in the list of sites, and I've also manually added it, but to no avail. Does anyone know any good alternatives to bypass paywalls, or some way of troubleshooting...
