Frequently Asked Questions

1. System Requirements

While the TRTCLE site and player may work on older setups, we strongly recommend keeping your system as up to date as possible. Browsers and operating systems are constantly releasing bug fixes, security updates, and improvements, and it’s our responsibility to keep up with them as well. Using the latest browser version can always help to prevent weirdness with TRTCLE and the Interwebs at large.

We support playback in browsers that can decode H.264 videos in an HTML5 player. Due to rising security vulnerabilities, TRTCLE no longer supports Flash. If you’re using an older browser, system, or website, you’ll need to upgrade to continue watching TRTCLE videos.

Here is a list of our supported browsers/versions:

1. Chrome 30+ (has automatic updates)

2. Firefox 27+ (has automatic updates)*

3. Internet Explorer 11*

4. Microsoft Edge

5. Safari 9+

*H.264 video (required for viewing TRTCLE videos) is only supported in Firefox for Windows 7 and later. Firefox versions on Windows XP are no longer supported for playback.

*Older versions of Internet Explorer (IE 10, 9, 8, etc) that lack support for the TLS 1.2 protocol and HTML5 cannot be used to play TRTCLE videos. As of January 12, 2016, Microsoft has stopped releasing updates to older versions of IE.
