Subscription link

I can’t see how to subscribe. The subscription link on the home page only tells you that you’re not a subscriber and doesn’t provide a link. It tells you to use the extension to subscribe but doesn’t tell you how. Does anyone have a link?

Hello. If you hit one of these buttons in the extension, it will tell you about ‘Pro’ mode and ask you to pay. You can use the extension in free mode though, if you like.
