Hi, iv'e actually had this problem for few months now, and have thought that Roll20 would resolve these issues. But apparently this has somehow not been fixed. My problem is as in title, i use mozilla firefox on windows 10. Been looking through forums, tried fiddling around with mozillas settings and addons, but nothing seems to work. And before you say "change the image to JPEG", yep done that. Done everything same as ever when it worked. As annoying and weird as this is. I do have this that i found in console after i tried to upload a new PFP hope it helps, and happy week for you all.
