Hi, I am reporting that videos on Ebay do not play correctly when using Firefox. I am a business seller on ebay and have just spent £900 on a professional product video for our 1000s of listings. I have used Firefox as my browser for many years. However I have discovered that when viewing product videos on ebay on a laptop/desktop, the videos are significantly reduced in size for 3 or 4 seconds with part of a dialogue box showing and then suddenly increases in size (still not full size though). Very unprofessional looking, very glitchy, very ugly. It would discourage sales rather than encourage them. Please investigate and fix asap. Ebay support tried all main browsers, yours was the only problem. Thanks, Simon, Libra Classica Bookbinders.
