I need a tutorial that would cover all aspects of Firefox Developer Tool as shown after pressing F12

I need a complete tutorial in pdf that would cover all aspects of Firefox Developer Tool in some detail as shown after pressing F12 in FF.

I don’t know about such PDF, but our documentation on MDN is pretty extensive: https://developer.mozilla.org/en-US/docs/Tools

This is good but it is scattered across many places/links. What I would like to have is a single document.

as said before, we don’t have such thing.
you may try to use a web scraper to generate one, I think all the sub-urls are under https://developer.mozilla.org/en-US/docs/Tools so you could exclude any other link.

We’re going to revamp this documentation later this year, so I’d be interested in knowing why you need everything on one PDF? Thanks

At best, I would like to have a hard reprint of a book covering all of MDN (more precisely all the stuff appearing after pressing F12 at FF) which I could borrow in my library. Having one pdf is a preliminary step to this.I need a tutorial of this in fact.
