Exporting a playlist with 4000+ songs never ends

Hi, my playlist of favourite songs contains 4000+ songs. When I try to export it to a csv file the process never ends.
Is there a limit to how many songs a to-be-exported playlist can contain?
Or is this memory related? Browser related?
I use a MacBook Pro with macOS Mojave (10.14.6) and Firefox 73.0.1.
