Extract all keys/values from about:config

[Diorser]

May be to clarify.
"Config Export" extension proposed by therube is exactly what I was looking for.

Just be warned it is only compatible with Firefox 31.0 - 56.*

Script investigation is then still necessary for 57 and above.

I got dickvl code working in Fx 57 with a little tweak. (remove "2" in nsIPrefBranch2)

Now for Fx 57 (then no extension available), could you summarize what you call the "dickvl code" on which you apply a patch for Firefox 57 ?
Looks a little bit confusing.

Instructions for running dickvl's code in Fx 57:

* open about:config
* set browser.tabs.remote.autostart.2 preference to false
* set devtools.chrome.enabled preference to true
* restart

* open about:support
* is multiprocess windows disabled?
* if yes, then continue

* open browser console (ctrl+shift+j) in tools > web developer
* copy and paste code into browser console
* press enter to run

There is no need to fix the nsIPrefBranch2 issue. The author fixed it.

You previously missed the point I looked for clarity in your previous messages related to patches.
"The code" which works without any patch for Fx57 is then the this one :
Thanks.
