Reproducible: Always Steps to Reproduce: 1. Open the Downloads window 2. Push the Ctrl+A (I had 72 files) 3. Select from the popup "Open containing folder" 4. Explorer starts endless opening of the folders. Actual Results: A lots (endless in my example) of opened folders. Expected Results: The folder is the same for the most of the downloaded files. I think it could be good if Firefox opens just a single folder (from the settings: Downloads folder) with the all selected files on it. And don't open/select files in the other folders.
