It would be awesome if we could use desktop Firefox's Inspector and Style Editor to remotely inspect Metro Firefox chrome. (They already work for content in Metro Firefox tabs, just not for the browser chrome.) dcamp informs me that Fallen has a hack to make this work in Thunderbird, which might be useful.

The hack is just adding the style editor and inspector as global actors, see bug 928008.

This is the same approach used for Thunderbird. Since Metro has only one chrome window, we don't even care that this is limited to a single window.

I'd suggest adding a comment why this is needed, either pointing here or to bug 928018 so it can be removed later on.

Added a comment as suggested above (thanks!).

This adds devtools.chrome.enabled to our default prefs (off by default), just to make it more convenient to enable in about:config. It also cleans up a pref that was added in two different locations in DEBUG builds.

I've set "devtools.chrome.enabled" to "true" in Firefox 28 beta 2 in Desktop mode, on Win 8 64-bit. Could you please offer some guidance on how to see the Inspector while in Metro mode? Is there a specific shortcut?

Here are instructions for connecting the Inspector to Firefox for Metro: https://developer.mozilla.org/en-US/docs/Tools/Remote_Debugging/Firefox_for_Metro To run both desktop and Metro on a single computer, you'll need these instructions: https://wiki.mozilla.org/Firefox/Windows_8_Integration#Running_Desktop_and_Metro_Simultaneously

Thanks Matt for the links! With Firefox 28 beta 4 on Win 8.1 32-bit, I've tried to follow the steps from https://wiki.mozilla.org/Firefox/Windows_8_Integration#Running_Desktop_and_Metro_Simultaneously but without success. After creating a desktop shortcut for Firefox, I created a new profile named "desktop". Then, I right clicked on the shortcut -> Properties, and introduced -p desktop -no-remote in the Target editbox, after "C:\Users\user\Desktop\28 beta 4\firefox.exe". Then I started Firefox in Desktop mode. (all good until now) I'm having trouble at step 3, regarding the start of Firefox in Metro mode: I've right clicked in the taskbar the Firefox already open -> Properties, and typed -no-remote in the Target editbox, after "C:\Users\user\Desktop\28 beta 4\firefox.exe". But Metro doesn't start. I've also tried the ./mach run command in a console, but still Metro doesn't start. Is there something I'm missing here?
