RSF Censorship Detector
Extension for Firefox. Sources for the Chrome and Chromium version can be found here.
This extension has been developped by Brendan Abolivier and Clément Salaün during the Collateral Freedom hackaton organised by Reporters Without Borders and An Daol Vras. You can download it through the GitHub releases or the Mozilla addons website.
Its goal is to ease the access to the Collateral Freedom initiative, which replicates websites around the Web in order to make them available for everyone, including in the contries they're censored in.
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 RWB.
When connecting (or trying to connect) to a website for which a replicated version has been set up by RWB, 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.

About Collateral Freedom
To mark World Day Against Cyber-Censorship (12 March), Reporters Without Borders is launching “Operation Collateral Freedom” to unblock nine censored websites in 11 countries that are on its list of “Enemies of the Internet.”
To render these ten sites accessible to the public in these countries, Reporters Without Borders has created mirror copies and has placed each copy with hosting services in the cloud provided by Amazon, Google and Microsoft. The countries concerned could block these services but almost certainly will not. Blocking Amazon or Microsoft or any major cloud computing service provider would cripple the thousands of companies that use them every day. The economic and political cost of blocking the mirror sites would therefore be too high.
Operation #CollateralFreedom is the brainchild of GreatFire, an NGO operated by Chinese activists that has already created unblockable mirror sites of Deutsche Welle, Google and China Digital Times. GreatFire’s tools and technology are freely available online for anyone to use to combat online censorship.
