Cross-browser extension for Firefox and Chrome that suggests available reverse-proxy urls and/or mirrors for sites that may be censored. This extension and its list of mirrors is curated by BypassCensorship.org.

This extension is a fork of the RSF Censorship Detector extension developped by Brendan Abolivier and Clément Salaün during the Collateral Freedom hackaton organised by Reporters Without Borders and An Daol Vras. To learn more about RSF's Collateral Freedom initiative, visit their site here.

The extension will add an icon next to your address bar. Most of the time, this icon will stay unchanged, and clicking it will show a message saying that no replication of the current tab's website has been set up by BypassCensorship.org.

When connecting (or trying to connect) to a website for which a replicated version has been set up by BypassCensorship.org, the extension's icon will turn red. Clicking it will open a pop-up page with a button.

If you click the button, it will bring you to the replicated website.

If you want to contribute, please feel free to do so. The first thing to do may be to check the repo's issues. When you've found something to contribute on, just fork this repository, make your changes, and send a pull-request.

The list of mirrors is maintained in a separate repository found here. If you would like to add a new site or mirror to the list that this extension supports, just open an issue or pull request there.
