The Android Firefox Updates appear to have eliminated users ability to see the entire video image on the viewer's screen with latest updates. How do we view entire YouTube 16:9 video image in fullscreen using "Desktop Site" like we have for years? Currently the image stretches proportionately on wider than 16:9 phone screens to touch the left and right screen edges. This has the problem of pushing the Top & Bottom of the image past the edges of the screen. This is a problem and a lost and valuable feature. We can not see the entire video image any longer after this feature was broken in the last few updates. Please fix this going forward. I can not log onto a live stream on my phone any longer and see what my video completely looks like after I tap "Fullscreen". The image is currently being shown larger than what can fit on my screen. Super Annoying and Frustrating to no longer be able to get around this annoying behavior by activating "Desktop Site". Please Fix this soon or I'll be forced to use older versions of Firefox Android that works and never be able to update again.
