Unlock is a Firefox Add-on to bypass paywalls by redirecting an article to a webpage capture from archive.today (which also uses the URL archive.ph). This Add-on has no affiliation with archive.today. Currently only The New York Times, The Wall Street Journal, The Washington Post, The Intercept, The Miami Herald, Financial Times, The Atlantic, Bloomberg, and The Athletic are supported.

Be prepared to complete a Google reCAPTCHA.
If no archive exists be prepared to wait while one is created (this can take a minute).
