I was working on a script in the Console > Command Line and it somehow crashed Firebug. Firebug would no longer run it so I restarted the browser. All the code I was working on was lost. Is there a file that I can check to see if my code was saved to it?
In the future I'd like to know if I can persist my Command Line History.
Unfortunately the command line history is not persisted between browser sessions. There is a request for it, but because the Firebug project is officially discontinued, it won't be implemented anymore.
Luckily, the Firefox DevTools do store the command history between browser sessions. And it even works when the browser crashes in between.
