The console.table() method in Firefox displays tabular data as a table in the browser's debug console.
This works great for visual inspection within the console, however any attempt to copy/paste that table to any other application gives a messy/unusable result.
But simply adding "Tab" characters (eg. ascii 9) between columns, and Line Feeds (ascii 10) at the end of each row of the console.table() output, would result in no notable visible change, but the table would generally "paste nicer" into many other applications, including spreadsheets like Excel, and even pasting into plain text editors would be more tidy.
I think many people would find this quite helpful.
