Upload error Missing Temporary file using Firefox

So last week we had an issue with uploading media to our media library, so I added a temp folder and also added the code define('WP_TEMP_DIR', dirname(__FILE__) . '/wp-content/temp/'); in the wp-config file, and I thought it wasn’t working, because I use firefox, and was still having the issue, so then today I noticed that a user was finally able to upload the files today, however when I tried using firefox 74.0 64-bit, I still received the missing temporary file error message, so then I tried it in IE 11, and I was able to upload the file successfully.

Now I don’t use IE, because I don’t like it, but I’m not sure what I need to do, to be able to use Firefox and upload files without any issues, can you please help me with this?
