This was discussed years ago, but to the best of my knowledge, it was never added. It's a good idea though.

Hello, I don't now if is complete answer to your question but for analyze HTTP request you can use Save all as HAR. Woow! Googling a little I found something interesting I don't know about this before but helping others actually helps yourself :)

Dear Anna,

Firebug was a spectacular extension, but it's no longer compatible with Firefox Quantum, so you can't use it anymore. I don't think it had the ability to save the log to a file either to be honest.

The Firebug project isn't around anymore though. I believe that the advanced features that Firebug had were moved into the builtin Firefox developer tools.

A personal recommendation : Use Visual Studio Code It has IntelliSense and debugging tools for Javascript too It's an extraordinary editor with many features for a great variety of scripting languages. In my humble opinion offer more than Sublime Text and is completely free. Now, returning to your question: For Firefox I found this:

A suggestion to use right click in console panel, save your object as a local variable and copy it to your favorite editor I try it but don't  work for me! 

Another tool http://bgrins.github.io/devtools-snippets/#console-save see console.save It work but seems a little outdated to me. And for mobile and web app remote debugging I found this tool Jsconsole https://jsconsole.com/ A little tutorial here: https://www.youtube.com/watch?v=BEo8oJYey-M Hope this help, Have a nice day,
