Since the update I performed today, 4/27/26, I am unable to upload files to my NAS via the Firefox web browser on a Windows 11 PC. I can still do it via the Google Chrome browser so I am not completely crippled, but it would be nice if I could still use Firefox for this work. Any suggestions on how to fix this, or will it require the software itself to be fixed?

UPDATE: I have played around with the security options in Firefox without success. I thought it might be a certificate issue, but all the certificates on my NAS are good. To clarify from my first post, I don't get any error messages telling me what's wrong - no security warning or compatibility message - it's just that nothing happens. I drag a file into my NAS portal to upload to it, and absolutely nothing happens. If I do it in a Chrome browser it uploads the file as normal. Anyone else having issues uploading using Firefox?

Uploads via file picker should work. There has been a change around drag&drop: https://support.mozilla.org/questions/1579531
