Upload Issues using Firefox Nightly

Just enquiring if anyone else is experiencing problems upload things through Firefox Nightly. I first noticed it around a week ago. I was using ChatGPT and uploading images, drag and drop, and I could get one or two to work, after that, the uploading buffer wheel would freeze. Completley clearing the cache would fox the issue, but it would reappear after one or two uploads again. Same issue, uploading to Grok. Today I tried uploading a couple of images to the The Movie Database, and again, same issue. If I switch to Chrome, no problems. If I use Edge, No problems. Funnily enough, when the issue presented today and I tried to post here, I got locked on the Fastly Client Challenge and had to use Chrome to post here. (I don't know if thats related, but squirrely either way) I have reported the issue on Bugzilla, but just wanted to know if anyone else has this issue. Thanks in Advance. Oz.
