Firefox за Android Community Forum

For some days I have an issue with playing YouTube videos in Mozilla android browser: videos appear as if they were enlarged several times, and I only see a top left corner of the video in low resolution. Full-screen mode, "view for PC" browser option did not change it. I tried reinstalling app, also installed Firefox nightly - the issue remained. On the other hand, videos on other websites, YouTube in chromium based browsers, Firefox on other devices do not have this issue. What could it be?

I was prompted by my phone to review Firefox, and on a whim wrote "Slightly annoying how it'll sometimes just refuse to load a page, at least on my old phone, but still my favorite browser" I received a "developer response" requesting that I ask a question in here to investigate further. Issue is, I just got a new phone, so the bug might not occur on this new one - it's not something that happens all that often, but it's my impression that it's something that'll happen if the Firefox app has laid dormant in the background of my phone for a long time and I tab back into it. It was always fixed with a quick restart. My old phone was a Samsung Galaxy S20 FE 5G, if that matters. Again, it *might* occur on this phone too, it just hasn't yet, I just can't say for sure, as it's not something that happens all that often, but still often enough to be a little annoying. I can't reproduce it on my old phone because every single pixel in the screen is dead, hence the new phone. So there's no way I could test it.
