2. Open Inspector: Ctrl + Shift + C (for Windows & Ubuntu) or Cmd + Opt + C (for Mac OS X)

[Expected result]: Collapse/Expand pane button is properly displayed.

[Actual result]: Collapse/Expand pane button is not properly displayed.

Hey Marco! This issue was found while verifying bug 1266420; but, as far as I can see, it's a long standing bug, definitely not a recent regression.

seems pseudo-class(::-moz-dir) with pseudo-element(:before) does not work

Does it a bug of pseudo selector, or should I assign image in code instead of in CSS?

Your approach should work, it's just a matter of choosing the right selector :)

::-moz-dir has been replaced by ::dir. ::dir only works on HTML documents, while ::-moz-locale-dir works for XUL documents.

-moz-locale-dir works, thanks! I was thinking the div button is a normal html element :/

It is, except inspector.xul is a XUL doc.

Can you change this to .sidebar-toggle:-moz-locale-dir(ltr) ?

Does the sidebar have a different location (top instead of bottom) on RTL for widths < 700px ? If not, can you remove this ?

done

In RTL mode the icon is changed to the conter-part, so the icon has to rotate in counter direction as well.

I think this is worth adding a comment:
/* Since RTL swaps the used images, we need to flip them the other way round */

Verified fixed with latest 50.0a1 RTL, under Windows 10 64-bit, Ubuntu 16.04 64-bit and Mac OS X 10.11.

Comment 22

[Itiel]

Fixed, but only for the Inspector tab. I guess the same patch should be applied to other tabs (such as Debugger, Network Monitor and possibly more).
Can it be addressed here or should I open a new bug for it?
