HTTPS/Browser Recommendations

Wikimedia encourages its readers to use modern web browsers which support secure internet connections. Below are recommendations for how to update to a modern web browser.

Many older computers, mobile devices or web browsers only support outdated cryptographic methods that are becoming insecure in the face of modern attacks. Wikimedia will no longer support these outdated cryptographic methods to ensure security against eavesdropping and interference (man-in-the-middle attacks or downgrade attacks). Many other sites on the Internet also require (or will soon require) a strong minimum levels of cryptographic abilities from your computer or mobile device. Keeping up-to-date with security updates from web browsers and operating systems will be essential for staying secure and continuing full access to all websites on the Internet.

Advice

For all users

• Please make sure you have applied the latest security updates to your operating system and have updated your web browser. Remember that for most browsers and devices, they will only be updated after you fully close them and restart them.
• Disable or uninstall any 3rd party "anti-virus" software. Most of them do more harm than good when they interfere with your browser's secure connections.

For IT personnel that manage outbound Proxy appliances

Please ensure you are running the latest stable software release from your vendor, and that you keep up with this regularly. Please also consult your vendor and/or their documentation as to how you may need to configure your outbound proxy to support stronger encryption/ciphers. See HTTPS for technical requirements.

Logs for Wikipedia have indicated that there are many requests from corporate desktop browsers that meet the version requirements of operating system, web browser, and device - but still suffer from downgraded cipher choice when communicating over the Internet due to outdated or poorly configured outbound proxies.

You may use an online tester to check which ciphers are supported by the browser you are currently using, such as the one provided by Qualys (SSL Labs).
