Simple problem; complex solution? I work between two laptops and send files from one PC to the other by email. This week I could not download the sent files on Yahoo Mail. It literally just stopped downloading. I checked my security settings, created an exception for Yahoo Mail, double checked MS Defender, but nothing seems to be blocking it that I can see. I tried to review other sources, but could not find something for this situation. Help?

On Windows 11 24H2, Firefox 145.0.2, I click file link and select "Save as" on Firefox file open dialog, firefox display "Windows's file dialog was crashed. File will saved as C:\Users\xxx\Downloads\xxxxxxxx.xxx". And downloaded file size is 0. This occurs with any file.

I tryed same operation on troubleshooting mode, and same result. Please tell me the solution.
