I have created a very basic export script that also works with the browsers "Google Chrome" or "Edge" or "Opera" (in addition to FireFox). A click on the column header sorts all the rows ascending - and with a second click on the same column header - in descending sort order.
It's up to you to prettify it with colors and fonts or rearrange the columns or add/remove columns and content.

It currently looks like this
