I have a website made with Wix. I have never had problems watching the videos uploaded there until the last update of FF. I can see all the old videos completely but only partially the new ones. That is strange. I asked Wix, and they told me their app works better on Chrome and Edge, so I opened my site in Chrome and Edge and the videos played complete. This problem happens in my PC and in my Android, and only with the last videos I uploaded to my site, which are mp4 type. The site is personal, so I hesitate to give the address to any not related to me, but this time I'll trust on FF volunteers and hope they will act professionally. The address is https://rdz.rocks and the last 2 videos are on My Hobbies/My Music/Christian Music/Vida Eterna and the problem is with the last 2 ones.
