When using Mozilla Firefox 37.0.2, I frequently encounter these related problems when using the UploadWizard.
- When clicking on the "Upload" button, the file selection window that opens sometimes does not show thumbnails properly. Closing the window, refreshing the web page, and clicking "Upload" again sometimes solves the problem.
- After the files have been selected, the website is unable to retrieve thumbnails of the images. Either a black rectangle appears, or a "broken image" icon.
- After the files appear to have been loaded and I click "Next", on the "Release rights" webpage when I need to declare whether the files were all created by me, sometimes some of the files selected on the previous page are missing. Occasionally, all the files are missing and the page presents with no buttons at all.
Occasionally, trying to use the UploadWizard causes Firefox to crash.
