When pressing the download example.csv button in firefox, it downloads a bunch of html in a .csv file.
When pressing the same button in google chrome, it downloads the proper .csv file.
Also, when choosing right click into 'save link as' in firefox on the button, it then saves it as the intended .csv file.
Attaching examples, example.csv is the proper one, example1.csv is the one from firefox.
example.csv
example1.csv
