To add a new site, enter an unique title/domain (without www.), select options for useragent (like Googlebot)/block Javascript (block on (sub)domain(s) of site and/or external domains) and/or set referer (ignored when Googlebot is set).<br>
Custom sites are enabled automatically in <small><button><ahref="options.html"style="text-decoration:none;color:inherit">Options</a></button></small> (cookies will be removed by default unless you enable allow_cookies).<br>
If you want to use custom sites (for non-listed sites) enable it in <small><button><ahref="optin/opt-in.html"style="text-decoration:none;color:inherit">Opt-in</a></button></small>
You can also just request permissions for the custom sites you added yourself (below).<br>
On Android: to enable custom sites you need the 'custom' add-on version (with access to all sites): <ahref="https://addons.mozilla.org/en-US/firefox/addon/bypass-paywalls-clean-custom"target="_blank">Bypass Paywalls Clean (custom)</a>
