I have been facing problems playing YouTube videos since the beginning of using it, maybe it was due to uBlock. But Today I can't play videos anywhere on YouTube, Facebook or Instagram. It shows loading but doesn't complete and doesn't play. I've turned off every extension and reverted to default settings, but it still doesn't work!&nbsp;<BR />I am using version 148 of Android.&nbsp;</P> Sat, 28 Feb 2026 14:02:29 GMT jehad_husein 2026-02-28T14:02:29Z https://connect.mozilla.org/t5/discussions/failed-to-play-video/m-p/118970#M46558 <P>Hello, I am facing many problems while using Firefox.
