You may need a proxy to watch the video.

I found a way to bypass the 10-minute restriction of Fox news live channel.

The simplest way

You need to delete browser's local storage every 10 minutes, manually.

Tools: Chrome

• Open Fox news video
• Switch to the "Watch live"

• Now you can watch the free preview of Fox news live

• If the 10 minutes run out, press ctrl+shift+i ( command+option+i on Mac)
• Switch to the Application panel of Chrome Dev Tools, unfold the Local Storage

• Right click the "http://video.foxnews.com" in the Local Storage, then click "clear".

• Close Chrome Dev Tools.

• Refresh the current web page. Enjoy another 10 minutes preview.

Tip: You can open the CC/Subtitles in Setting button

Another troublesome but good way

Tools: Chrome, HLS extension

• Open Fox news video

• Switch to the "Watch live"

• Find the URL of m3u8.

  • press ctrl+shift+i ( command+option+i on Mac)
  • Switch to the Network panel of Chrome Dev Tools
  • type m3u8 in search bar
  • right click one of the m3u8, copy link address.
  • 

• do not close the former tab, paste the URL of m3u8 in a new tab of Chrome.
  The m3u8 URL I get is http://fnctve-i.akamaihd.net/hls/live/200669/fnctve/HD.m3u8
  You need install the HLS extension

• now you can close the tab of video.foxnews.com.

if you cannot get the m3u8 URL, see above, try to clear local storage of video.foxnews.com, then refresh
