Can't upload to Google Photos
Firefox 75.0 (64-bit)
Have just re-installed Firefox on Windows 10 and find that I can't upload images to Google Photos. However - I can upload if I use a "Private Window".
I have deleted all user data and tried re-installing Firefox, but this hasn't fixed the issue.
I have no add-ons installed.

I have a similar problem on Linux mint Tricia 19.3 Cinnamon. Through Chromium, downloads work, through Firefox gives an error loading files!

Okay..... this isn't a Firefox issue as such. Uploading to Google Photos works 100% OK on any Chromium based browser - Bravem Edge, Opera, Chrome. Just not on Firefox. So the issue is at Google's end. Have tried asking on the Google help site, but as usual nobody has a clue.
This is a bit of a pain, but I suppose the only solution is to use an alternative browser - I can use Edge to upload, since my Windows 10 machine already has it installed.... anything rather than Chrome!
Linux users could use Opera or Brave.
