I can enter the file URL "file:///sdcard/video.mp4" and the video plays just fine. When online it also brings up "www.file.com" in the window, which would be best that it didn't. When I pass the same URL from another app, the URL bar shows "http://www.file.com///sdcard/video.mp4", when online. When offline, it shows "http://file///sdcard/video.mp4". Consequently the video doesn't play. I have tried the same with 9 other browsers and the substituted URL is different, so I assume that it is the browser doing the substitution rather than the app. I want to play the video from the app through FireFox whether offline or online using the same URL that works directly. Thank you, Bob
