'''Firefox 139.0.4. '''version is also not good! '''Uploading videos to Youtube does not work with it! '''It does not move from zero percent! As I wrote earlier, the problem started with version '''138.0.4.''' and is still ongoing! '''Uploading videos works with other browsers!''' I am waiting for the problem to be solved! If I wrote my letter in the wrong place, please forward it to the authorities! At the moment I could write a letter here, I can't really find a topic where this would be discussed! My OS Win10 64 bit. Thank you!
