auto play videos

Firefox is my favorite Browser because I have been able to customize it tremendously so that things do not buzz and blink and pop up at me, nothing flashes, nothing makes noise unless I deliberately permit it. today I caught Firefox for mobile permitting a video to auto play. I opened a webpage to read an article and suddenly realized that my podcast (from a different app) had been interrupted and now sound was coming from this page (clear from the content of the sound). I literally had not even seen the video in question as part of the page because I had not scrolled down far enough to where it was playing already. And when I had the lock screen on, clicking pause did not stop the video. So Video was playing without my permission, and was ignoring the usual rules of iOS. I certainly had not clicked on the video or seen any setting that allowed the website to autoplay videos. And this is not the first time it has happened, but it is the first time that I am positive that I did not do anything to permit this behavior, and that it had to have been the browser automatically playing something on the page. I verified that the same website does not auto play video in Safari. This is a bug in Firefox Browser for iOS .... unless there is some new setting in an updated version of the browser that says 'please bombard me with autoplay at times" which by default was switched on in a recent update.
