Hello everyone! Since the release of the new Firefox version 90 afterwards I have been using Firefox as I simply love surfing the internet with it as an alternative to chrome or chromium based browsers. However, a small problem is annoying me: when I try to upload to iCloud.com or Google Drive, especially large ones, the upload speed is limited to 10 mbps, whereas I have an upload speed of 50 mbps. On the other hand, when I try to upload on Chrome Browser or Edge Browser to both websites, the speed gets maxed out, literally maxed out by even 55 mbps! I even tried to upload similar sized files simultaneously to Chrome, Edge and Firefox. Chrome and Edge finished while Firefox is still stuck on one third of the upload! The strange thing though: when I open speedtest.net and measure the upload speed, it gives me on Firefox a speed of 50 mbps! Any idea where the problem is? Any ideas how to speed up the upload and benefit from the max speed? I am using latest Firefox on Windows 10. Thank you!
