Video not showing in FireFox

Share your site link to check the issue of videos not playing in the FireFox browser, so that I can check and do the needful.

Also, I get this error in browsers:

Warning: mysqli_num_fields() expects parameter 1 to be mysqli_result, boolean given in /home/tekken5/public_html/wp-includes/wp-db.php on line 3021

I have the paid version, so I’d really like some help.

Hello?

I checked the site and noticed that the YouTube Iframe code is not binding in the FireFox browser. So contact our support at [email protected] to fix the video not playing in FireFox issue and warning message displayed on the site.
