We have a normal file upload control in our website. It was working fine for smaller and larger files. But after upgrading firefox version to 100, it is not working. If file size is less than 250 kb then it works sometimes.

For older Firefox versions and other web browsers (Chrome, Edge) it is still working fine.

No error coming at UI/web console:
