A possible workaround is to do a copy and paste in the Scratchpad. You can make a button appear on the toolbar via the settings page (F1).

Thanks. Thats a neat tool I didnt know about.

However, the point is. The button used to be there in previous versions of Firefox. Now it is not (even it is present in documentation). I ask why. I ask to return the button. It is super useful!

I checked about:config to find out: devtools.debugger.new-debugger-frontend;true devtools.debugger.pretty-print-enabled;true devtools.debugger.auto-pretty-print;false

So i think, there is a bug. Is this right place to report a bug? Thanks:)

To make it even more weird, I realised there is the button when I open debugger on this page. Unfortunatelly, it doesnt work. Further, there is no button on other pages (eg. bitbucket.com).

And `devtools.debugger.auto-pretty-print;true` doesnt work neither.

Try:

• devtools.debugger.new-debugger-frontend = false

That works, thanks!

The documentation is wrong then.
