For the past several months, I've been unable to use the new HTML5 uploader. When I try to batch upload several images at once, it looks like it's processing the first image, but gets stuck every time. I've tried resizing the images below the maximum image size, but it still gets stuck. I tried emailing tech support last week, but had no response.
My son took a look at it today, and told me to write what my browser and operating system is. I am using Firefox 22.214.171.124, and my OS is Windows 10. Also, that when it got stuck, he checked a developer console and saw a very large amount of errors that said "NS_ERROR_FAILURE" (it started around 400 and kept rising into the thousands and didn't stop after several minutes).
I read the forums, and it sounds like that maybe other people are having similar problems with their uploads? Can somebody please address this issue?
