will not play HTML5 content

Posted

using Firefox 57.0 Mac OS 10.11.6 El Capitan

I subscribe to a website that uses primarily HTML5 content. ("The vast majority of our cards do not require Flash: they use HTML5 and/or video formats instead") This will not play on my computer. Researching this I found an extension titled HTML5 Video Everywhere ( developer: lejenome) and installed. It is listed in the Extensions tab and enabled. I have quit and re-opened Firefox several times. Video content from this website still does not play. This content DID play prior to the v.57 update on Nov. 15. What is wrong??????????

Hello,

The Refresh feature (called "Reset" in older Firefox versions) can fix many issues by restoring Firefox to its factory default state while saving your bookmarks, history, passwords, cookies, and other essential information.

Note: When you use this feature, you will lose any extensions, toolbar customizations, and some preferences. See the Refresh Firefox - reset add-ons and settings article for more information.

To Refresh Firefox:

  1. Open the Troubleshooting Information page using one of these methods:
    • Click the menu button New Fx Menu , click help Help-29 and select Troubleshooting Information. A new tab containing your troubleshooting information should open.
    • If you're unable to access the Help menu, type about:support in your address bar to bring up the Troubleshooting Information page.
  2. At the top right corner of the page, you should see a button that says "Refresh Firefox" ("Reset Firefox" in older Firefox versions). Click on it.
  3. Firefox will close. After the refresh process is completed, Firefox will show a window with the information that is imported.
  4. Click Finish and Firefox will reopen.
